I am supplied data by a third party company in the form of self extracting EXE archives.
Take example:
fvdata.exe
When i extract this archive on my windows machine I get this(this is what I am trying to achieve):
fvdata_d
however on my CentOS 6.5 machine I get two folders:
fvdata_d FVdata_d
I believe the tech putting this archive together was a bit sloppy when it came to their case sensitivity. However I am not sure how to fix this.
Commands I have tried on the linux machine to extract:
7za x fvdata.exe -y -ssc-
unzip fvdata.exe -C
unzip fvdata.exe
If I can't do this maybe someone can reccommend a work around?
In unzip, the -LL option forces conversion of every filename to lowercase, regardless of the originating file system.

My apology for the "newbie trouble" that I created for myself & apology for my poor command of computer lingo
I am running a Windows 7 laptop and have a big text file (~4Gb) that I need to find certain string.
Most programs in Windows 7 cannot handle the task (file too big to open in any program in the Microsoft suite), so I downloaded cygwin and tried to grep the specific string.
The problem is
(a) the 4 Gb file is stored in the desktop of my non-admin account.
(b) I assume cygwin runs in the admin account (although I use the desktop cygwin icon to launch the environment). The reason being that under cygwin, I see the handle A#Admin-THINK (running it on a Lenovo Thinkpad laptop)
grep the file of interest results in "No such file or directory"
I tried to find the path of the file (readlink, realpath) but guess the commands were not applicable here?
Also tried /home/A/file or /home/A/desktop/file but it is clear that my random guess fails.
From windows, the file should be in
C:/Users/non_admin/desktop/folder/file
What would be the right path of the file to grep the string using cygwin ?
You can use /cygdrive to access the Windows filesystem. In your case, try
grep foo /cygdrive/c/Users/non_admin/Desktop/folder/file
From windows, you can get the correct file path from the context menu item Copy as path into the copy/paste buffer.
In Cygwin mintty, use
FilePath=<paste>
where <paste> means to use paste from mintty's context menu to make a variable with the value of that path.
Then use
grep <string> $(cygpath -u "$FilePath")
to search the file. The "'s are in case the file name contains spaces.

I use a cluster (OS is Linux) which does not have R. I would like to install R in my personal folders so that I can just do
Rscript example.R arg1 arg2
How should I install R on this cluster knowing that I don't have admin rights?
How can I then manage the packages?
I'm not sure this is on-topic, but: all you really have to do is
download the R source tarball from CRAN; unpack it somewhere in your file space
create an r-build directory at the same level of the hierarchy (not technically necessary, but it's better practice to keep the source and build directories separate)
create an installation directory (say ~/r_install) somewhere sensible within your file space
cd to the source directory; tools/rsync-recommended
cd to the build directory
../[srcdir]/configure --prefix=~/r_install
make (to build the binaries)
make install (to move everything where it belongs; not technically necessary, as you can run R from the build directory)
Where this may get hairy is with all of the system requirements for R (LaTeX, Java, bzip2, etc. etc. ...) it is theoretically possible to download all this stuff and install it in your own file space, but it starts to get sufficiently tedious that it will be easier to beg your sysadmin to install at least the dependencies for you ...
as #Hack-R points out the basics of this answer are already present on Unix & Linux stackexchange, although my answer is a little more detailed ...
I am a newbie to UNIX, i want to print tree structure of files in a directory. below image is example in DOS, what will be the command of Unix to achieve same objective
I think you are looking for the "tree" command. If you are having issues running it you might have to find out how to install it on your specific distribution. For ubuntu installs you can find instructions here:
https://askubuntu.com/questions/507588/not-able-to-install-tree-comand-in-ubuntu
Not sure what you mean by "on Unix". What OS are you running, specifically? Tree should be compatible on Unix systems. You may just have to compile it for your particular OS.
This command prints output like the following (on cygwin):
I wrote a .spec file on RHEL and I am building RPM using rpmbuild. I need ideas on how to handle the situation below.
My RPM creates an empty logs directory when it installs first time within the installation folder like below
/opt/MyInstallation-1.0.0-1/some executables
/opt/MyInstallation-1.0.0-1/lib/carries shared objects(.so files)
/opt/MyInstallation-1.0.0-1/config/carries some XML and custom configuration files(.xml, etc)
/opt/MyInstallation-1.0.0-1/log--->This is where application writes logs
When my RPM upgrades MyInstallation-1.0.0-1, to MyInstallation-1.0.0-2 for example, I get everything right as I wanted.
But, my question is how to preserve log files written in MyInstallation-1.0.0-1? Or to precisely copy the log directory to MyInstallation-1.0.0-2.
I believe if you tag the directory as %config, it is expected that the user will have files in there, so it will leave it alone.
I found a solution or workaround to this by hit and trial method :)
I am using rpmbuild version 4.8.0 on RHEL 6.3 x86_64. I believe it will work on other distros as well.
If you install with one name only like "MyInstallation" rather than "MyInstallation-version number-RPM Build Number" and create "logs directory as a standard directory(no additional flags on it)[See Original Question for scenario] Whenever you upgrade, you normally don't touch logs directory. RPM will leave its contents as it is. All you have to do is to ensure that you keep the line below in the install section.
%install
install --directory $RPM_BUILD_ROOT%{_prefix}/%{name}/log
Here, prefix and name are macros. That has to do nothing with underlying concept.
Regarding config files, the following is a very precise table that will help you guarding your config files. Again, this rule can't be applied on logs our applications create.

I am trying to provide a means of allowing people to upload zips and have them extracted to a particular file path. It seems like zip functionality has been added in Lasso 9 but I'm curious if there is in fact a method for doing this in 8.6 or if anyone has any suggestions.
There are a couple of options (besides upgrading to 9):
First, you could use [os_process] to call the unzip command-line utility and have it do it for you
In 8.5, there was an example for the LJAPI documentation that created a [zip] custom type that you should be able to use. (I'm not sure if the 8.6 installer has it, but for OS X, after installing 8.5 you could find it here: /Applications/Lasso Professional 8/Documentation/3 - Language Guide/Examples/LJAPI/Tags/ZipType/) Chapter 67 of the Language Guide has documentation on how to get it installed and working.
Further expounding option 1 in bfad's answer: You might like the Lasso 8 shell tag from TagSwap to make this even easier. Here's an example where I extract tar'd and gzip'd archives:
// authenticate with user that has file permissions in this directory
inline(-username='username', -password='password');
// load shell tag from TagSwap
library_once('shell.inc');
// call tar from bash shell
shell('tar -zxf myfile.tgz');
/inline;
