I am using a Mac Book Pro with El Capitan installed. Yesterterday I was trying to change a file permission and I made a very big mistake.
This is the command I issued
`sudo chmod -R 777 /`
After issuing the command the system began to give many system errors. I restarted my laptop and now it keeps stack at the apple logo with the progress bar.
I have been able to go to the single user mode, buh I dnt know how to get the laptop to boot normally.
Anybody with an idea on this can help me. Thanks
You should definitevely check this post about your problem here. (Apple's Repair disk permissions with Disk Utility)
I don't think it will repair everything though...

I'm pretty rookie to this, but I managed to get this code running when I had a PC.
Now I want to get this working on my MacBook.
I'm using Rclone to sync to Jottacloud, and I want to make a clickable file, just as a .bat file in windows.
This is my simple code:
#!/bin/bash
cd /
cd /Applications/rclone
rclone copy /Users/windsvendsen/Pictures/Billedebank Jottacloud:Billedebank
Running it in Terminal, without the #!/bin/bash, it works as it should.
But when I save it as a file, without extension, and running chmod 744 on it, it returns with the error "No such file directory"
And here does my knowledge end.
It is probably a pretty simple problem, but I do not manage to get the essence out of my google searches.
Thanks in advance!
Can you do ls on the directory and see if the file actually got created
I am new to these forums and to using Ubuntu and linux and UNIX. I really need some help here. I hope I haven't shot myself in the foot already. I have been trying to complete a UNIX carpentry lesson on the internet for an assignment. I am learning the basics about UNIX. I am not using a Mac, I am using a PC that I did not configure in any way (maybe that's my problem). I am using windows 10 on a lenovo and trying to the command prompt on Ubuntu to find my desktop where a file called "data-shell" is located. The problem: IT IS NOT FINDING THE DESKTOP. Upon further inspection, I have been looking through the location of my desktop and "data-shell" file and found it in the Users location under a number 12094, which I am assuming is the serial number for the computer. I have NEVER fiddled with the software at all with this computer as it cost me a lot of money, but I really do not want to be stopped in the tracks already. I have the following images numbered in the order that I discovered everything; they are posted here. I would really appreciate the help. P.S.: Since I am using a PC and not mac, I thought I had to use another command line like BASH or the terminal on my PCor doI just use Ubuntu? The UNIX shell is supposed to start with a $, right? Please correct me if I a wrong and thank you for your help
.
linux commands on windows can be ran via cmder or git bash (what i had used in past)
and in linux the desktop is at the path
/home/< username>/Desktop
whereas in windows its
C:\Users<username>\Desktop
both windows (DOS) and ubuntu/mac(linux) environment are entirely different you can directly run commands of one on the other environment, you do need to "setup" that env first if the command is not native to that.
Now, since its assignments that you are doing and all you need is bare-min linux env
you can give https://repl.it/ a try and create a new project in bash
Also, when you install Ubuntu on windows you dont get acces to windows like path, like "C:...", in ubuntu c:\ of windows is mounted to some other path in ubuntu
search on google how to access windows desktop from ubuntu shell after installing ubuntu inside of windows
When using Windows Subsystem for Linux (WSL), your C drive is located under /mnt/c.
Judging from the screenshot, you are user 12094, so you can either accept this, or you need to actually configure your machine. Also if you look in the screenshot you provided, there is a /home folder which I am betting is actually pointing to /mnt/c/, and your home folder will be under /home/12094, which is also the same as what is stored in $HOME.
To find the location of a file called data-shell, you can run the following linux command while in your home folder:
find $HOME -type f -name 'data-shell'
This command recursively searches for files in your home directory, with the name data-shell
I was trying to set a new home directory for Cygwin, but the thing is I've managed to do so only partially.
I changed the 'db_home:' parameter (cygwin64/etc/nsswitch.conf) to '/windows' so it now matches the win10 default home folder, but the trick works only if mintty.exe was run through cmd.
Running mintty manually with a desktop shortcut results with the very same default directory as if the file was never changed.
Having all that said, I'm a total newbie when it comes to both Cygwin and Unix in general, so it's very likely I missed something obvious.
I appreciate any help provided, thanks in advance.
I am trying to upload a directory from my local machine to a Digital Ocean droplet, ubuntu 14.04, using the command "put -r myDirectory". Initially I had the "unable to canonicalize path" issue, but I created a remote 'myDirectory' as instructed and the error message disappeared.
However, "put -r myDirectory" still doesn't work - the console prints "Uploading myDirectory/ to /remote/path/myDirectory, Entering myDirectory/" and then nothing happens. I am new to sftp but I'm very puzzled as I can't find my problem on the internet.
Well - I'm currently running into the same problem.
It seems that this OpenSSH bug report may have a lot to do with it:
http://lists.mindrot.org/pipermail/openssh-bugs/2016-January/015929.html
I'm running on Ubuntu 15.10, OpenSSH version 6.9p1. They seem to have fixed it in this commit from Feb 11, but I'm not sure yet how to get it running in my current environment.
Using
put /mydir/*
worked for me.
When I start Java application from command line on AIX 6.1 machine the application just doesn't start. All I get is a blinking cursor, hitting CTRL+C doesn't help. It seats in the list of processes all the time.
Even running the following command produces the same result so I don't think it is program related.
java -version
Cursor is blinking on the next line and nothing happens. When I open second session and type
ps -ef
I get the following:
tomcat 32243914 31850686 0 13:50:27 pts/7 0:00 -ksh
tomcat 5439538 32243914 1 13:50:50 pts/7 0:00 /usr/java6/jre/bin/java -version
On Windows my program runs just fine. So I think it is JRE or Unix related.
I'm not a Unix expert so I would appreciate any suggestions on how to trouble shoot this.
sounds strange , it seems that your process does not give hands back... No return
Do you have top binary installed on your AIX machine ?
Could you check that this machine follows the long list of requirements to run the java binary ? You may find useful information on the IBM java package webpage I guess...
Do you have lsof binaries or any other standard debuging tool ? lsof would point to any problem related to your AIX machine
HTH

We have an intermittent similar issue with Java on Solaris. Sometimes rebooting the machine helps. Other times we have to remove the .java file from the user's home directory. Very random and annoying. The box can be up for months before it happens, or mere hours...
