I'm trying to add a directory to my $PATH in mac OSX.
echo $PATH produces:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin
logged in as user and doing: vim ~/.profile shows a different set of paths and adding to it doesn't change the path echo'ed from: echo $PATH (in a new shell)
I have looked in ~/.bash_profile and its not there.
I've tried looking around when logged in as sudo su - but I can't find where the above path is set for me to edit it.
echo $env shows a blank line.
You should add the path to .bashrc and also to source it from your .bash_profile like so
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
That way, when you set a PATH, it will apply to both.
Now when you login to your machine from a console .bashrc will be called.

When I start tmux, my ~/.config/fish/config.fish seems to be sourced again. This means any set PATH foo $PATH statements in my config get executed again, which leads to my PATH variable having duplicate entries in it. This isn't drastic, but it is annoying to ECHO path. when it is so long
How can I prevent this problem?
EDIT: the only fish related entires in my tmux file are
#fix vim
set -g default-shell $SHELL
set -g default-command "reattach-to-user-namespace -l ${SHELL}"
set -g default-command 'reattach-to-user-namespace $SHELL --login'
The ~/.config/fish/config.fish config file is read by every new fish instance. There are several ways to achieve what you're asking. One option is to always set PATH from scratch. That is, don't modify the existing path by appending or prepending to it but instead set it to exactly what you want for a given machine. Something along the lines of
set -gx PATH $HOME/bin /usr/local/bin /usr/bin/ /bin
test -d /opt/X11/bin
and set PATH $PATH /opt/X11/bin
Another option is to add directories only if they aren't already in the path:
contains /usr/local/bin $PATH
or set PATH /usr/local/bin $PATH
Or only do the modification if not inside a tmux session:
if not set -q TMUX
set PATH /argle/bargle $PATH
end

This has been happening, after I foolishly edited the .zshrc file. All that remains in the file now, after attempting to reset the shell, is this:
# Created by newuser for 5.3.1
# Add env.sh
How do I undo everything, reinstall zsh, or remake the .zshrc file?
This is on macOS Sierra.

zsh itself does not have a default user configuration. So the default ~/.zshrc is actually no ~/.zshrc.
But as you tagged the question with oh-my-zsh I would assume that you want to restore the default oh-my-zsh configuration. For this it should be sufficient to copy templates/zshrc.zsh-template from your oh-my-zsh installation path, usually ~/.oh-my-zsh:
cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
You may want to backup your current ~/.zshrc beforehand. Although it may have some problems now, you still might want to look up some settings once you reverted to default.
There is no such thing as "default". The best you can do, is check if your system has /etc/skel/.zshrc. If yes copy that into your home.
When you log in first time, your home is populated with everything from /etc/skel.
My dumass decided to just put a crash command into the zsh file. Now when I open the terminal, it just kernel panics. so I just deleted the config file using rm -f ~/.zshrc* and by default, it just got replaced with another copy. So good luck.
You can copy .zshrc template from
https://github.com/ohmyzsh/ohmyzsh/blob/master/templates/zshrc.zsh-template
And copy and paste all content in to ~/.zshrc
[MS Windows Friendly Solution - If terminal(using vim editor) steps are confusing]
Actually, there is no default .zshrc file, but if you need to edit is as a simple notepad, do these:
Goto /Users/ Folder via Finder App.
Click Shift + Command + . (Dot) to view hidden system files.
Look on .zshrc file, double click to open, then it will open in a notepad(TextEdit.app) in default.
Clear whichever lines to be removed.
Retype/Edit the file as per the Paths to be added.
Hit Command + s to save and exit.
Make it your default shell using this command:
chsh -s $(which zsh)
I run a .csh file in UNIX that contains the following script
#!/bin/tcsh -f
set path = "$1"
find "$path" -name myfolder
And get the following message
find: Command not found.
What am I missing?
Thanks
The $path variable is special - it tells the shell where to find tools like find. :-) Use a different variable name.
From your interactive shell, you can see what $path normally looks like by echoing it. The following is my path on my FreeBSD server:
ghoti% echo $path
/usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin /home/ghoti/bin /usr/X11R6/bin /usr/games
If this list is replaced with something else, for example the contents of $1, then tcsh doesn't know to look in /usr/bin to find find:
ghoti% which find
/usr/bin/find
ghoti% set path = "hello world"
ghoti% which find
find: Command not found.

Just installed tmux via homebrew and I'm trying to locate the system-wide tmux configuration file. The man pages state that the system-wide file should be located in /etc/tmux.conf, but for some reason, it is not there. Where is the default tmux.conf file located?
Note: Currently running OSX Mavericks
As far as I can tell the tmux installed via homebrew does not have a system wide conf file. If you did need one you could add your own at /etc/tmux.conf. However, I would wonder the need for this. I place my config in ~/.tmux.conf and everything is very happy.
There is a /usr/local/Cellar/tmux/1.8/etc directory but it houses the bash completion scripts. I also checked usr/local/etc it it to did not have an installed config.
I'm pretty confident at this point that the tmux installer via homebrew does not install it's own system wide config file instead leaving that as an exercise for the sys admin if such a feature was required.
By default tmux doesn't have a system-wide config that is editable. It's complied into the program.
Use these commands to list out the compiled defaults, then make your own file with it for your user.
tmux list-keys # show current bindings
tmux show-options -s # show current server options
tmux show-options -g # show current global session options
tmux show-options # show current session options
tmux show-options -gw # show current global window options
tmux show-options -w # show current window options
With tmux 1.7, show-options can also show you the value of a single option (prior versions can only list all the options from the specified class):
tmux show-options -gw window-status-format
You should find something useful in:
/usr/share/doc/tmux/examples
recent versions of tmux only have the examples conf files, it's not an OSX issue, just new default tmux packaging. So you can use any of those doing something like:
$cp /usr/share/doc/tmux/examples/someconffile.conf ~/.tmux.conf
that should do it.
from the man tmux page:
-f file Specify an alternative configuration file. By default, tmux loads the system configuration file from /usr/local/etc/tmux.conf, if present, then looks for a user configuration file at
~/.tmux.conf.
If there is no file, you can just create one using touch ~/.tmux.conf and write whatever you want.
Alon Gouldman's answer worked for me. Just to add to it:
I had this issue when working on Ubuntu 20.04.
Here's how I solved it:
Firstly, if do not find any configuratio file for tmux in your home directory, then create one inside your home (~) directory using the command:
touch ~/.tmux.conf
Next, to make the file to be always available whenever you start a Tmux session add the file to either the ~/.bash_profile, ~/.bash_login, and ~/.profile file. It should be added at the bottom of the file:
source "$HOME/.tmux.conf"
Here's an example:
# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.
# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022
# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi
# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
PATH="$HOME/.local/bin:$PATH"
fi
source "$HOME/.tmux.conf"
Note: The ~/.bash_profile file takes the first precedence, then the ~/.bash_login file as the second precedence, and then the ~/.profile file as the last precedence.
That's all.
I hope this helps
"I will take a crack at it. Here are some solutions off the top of my head. I do not run Mac but I run RH, Debian, FreeBSD, and Solaris, CYgwin and other stuff.
My understanding which is taken straight from man tmux. The -f flag will specify an alternative configuration file. By default, tmux loads the system configuration file from /etc/tmux.conf, if present, then looks for a user configuration file at ~/.tmux.conf. The configuration file is a set of tmux commands which are executed in sequence when the server is first started.
#!/usr/bin/env bash
unset temporary_array_tmp ; declare -a temporary_array_tmp
temporary_array_tmp=(/etc/tmux.conf ~/.tmux.conf)
# The next line creates an empty global and personal configuration file,
# if it individually does NOT exists.
for i_tmp in "${temporary_array_tmp[#]}" ; do
[[ ! -f "${i_tmp}" ]] && \
touch "${i_tmp}" && \
echo -en "I created an empty tmux configuration file # ${i_tmp}. " && \
echo -e "You need to add configuration settings to ${i_tmp} ." || \
echo -e "The tmux configuration file ${i_tmp} already exists."
done
# After you add configuration settings, then you need
# to tell tmux to reload the files.
for i_tmp in "${temporary_array_tmp[#]}" ; do
[[ -f "${i_tmp}" ]] && \
tmux source-file "${i_tmp}" && \
echo -e "${i_tmp} The tmux configuration file ${i_tmp} is loaded." || \
echo -e "The tmux configuration file ${i_tmp} is NOT loaded."
done
unset temporary_array_tmp
Mentionable Notes
Next you can find tmux directories and/or files using find. For example:
find ~/ /etc /usr -iname *tmux*
In UNIX, I read that moving a shell script to /usr/local/bin will allow you to execute the script from any location by simply typing "[scriptname].sh" and pressing enter.
I have moved a script with both normal user and root permissions but I can't run it.
The script:
#! bin/bash
echo "The current date and time is:"
date
echo "The total system uptime is"
uptime
echo "The users currently logged in are:"
who
echo "The current user is:"
who -m
exit 0
This is what happens when I try to move and then run the script:
[myusername#VDDK13C-6DDE885 ~]$ sudo mv sysinfo.sh /usr/local/bin
[myusername#VDDK13C-6DDE885 ~]$ sysinfo.sh
bash: sysinfo.sh: command not found
If you want to run the script from everywhere you need to add it to your PATH. Usually /usr/local/bin is in the path of every user so this way it should work.
So check if in your system /usr/local/bin is in your PATH doing, on your terminal:
echo $PATH
You should see a lot of paths listed (like /bin, /sbin etc...). If its not listed you can add it. A even better solution is to keep all your scripts inside a directory, for example in your home and add it to your path.
To add a directory in your path you can modify your shell init scripts and add the new directories, for example if you're usin the BASH shell you can edi your .bashrc and add the line:
PATH=$PATH:/the_directory_you_want_to_add/:/another_directory/
This will append the new directories to your existing PATH.
You have to move it somewhere in your path. Try this:
echo $PATH
I bet /usr/local/bin is not listed.
I handle this by making a bin directory in my $HOME (i.e. mkdir ~/bin) and adding this to my ~/.bashrc file (make the file if you don't already have one):
export PATH=~/bin:$PATH
This may seem silly to mention, but did you make sure it is executable? Did you chmod +x script.sh? Does the shell script have the correct path to it's shell at the top (i.e #!/bin/bash)? Also, are you using UNIX or LINUX or FreeBSD? (last question is important)
To run executable from any directory:
1)Make a bin directory under your home directory and mv your executable scripts into it.
[root#ip9-114-192-179 ~]# cd /home
[root#ip9-114-192-179 home]# mkdir bin
[root#ip9-114-192-179 home]#ls
bin cloud-init-0.7.4-10.el7.noarch.rpm cloud-user epel-release-7-11.noarch.rpm
2)Move your executable scripts in bin direcoty.
mv preeti.sh /home/bin
3)Now add it to your path variable.And source it.
[root#ip9-114-192-179 ~]# echo 'export PATH="$PATH:/home/bin"' >> /etc/profile
[root#ip9-114-192-179 ~]# source /etc/profile
[root#ip9-114-192-179 ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/home/bin
4)Check if that path is added in path variable.
[root#ip9-114-192-179 ~]# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin:/home/bin
5)Verify if script is running from any random directory.
