I've been wanting to write a python script that would run several instances of rsync in sequence for backing up data to a different computer. At the moment I just have this text file with the commands I use and I've just been copy-pasting them into the terminal, and it seems kinda silly. I want to be able to use python to do this for m...
Hi folks. I've got a bash script that writes to a file. at the end of the script I want to display a menu, with line numbers - and have the user be able to select 1 or 2, (etc. up to the number of lines in the file) then have it execute that line. Up to here is perfect. However, after the line is executed (say for example it displays...

I'm trying to write a shell script that will list all the folders in a particular directory on the remote server. My question is: how do I specify the remote location? Here's what I've got: #!/bin/bash for file in [email protected]:dir/*...
I'm guessing this has to be an escaping issue, but I can't find it. What's most frustrating is that this is based on an old sed script I used that worked, so why can't I make it work when I try to re-use it a year later? ;) Framework: I have a file with a list of filenames in it that all need the same string of HTML searched and repla...

Is it possible to have a Perl script run shell aliases? I am running into a situation where we've got a Perl module I don't have access to modify and one of the things it does is logs into multiple servers via SSH to run some commands remotely. Sadly some of the systems (which I also don't have access to modify) have a buggy SSH server t...

Example: ./test.sh this is "some test" then I want to use those arguments, and re-use them, including quotes and quotes around the whole argument list I tried using \"$@\", but that removes the quotes inside the list. How do I accomplish this ? ...
I have a large (600 odd) set of search and replace terms that I need to run as a sed script over some files. The problem is that the search terms are NOT orthogonal... but I think I can get away with it by sorting by line length (i.e. pull out the longest matches first, and then alphabetically within each length. So given an unsort set o...

Hello all, I am attempting to write a bash script and I am having difficulty making the output look neat and organized.

For instance, when I run git clone ..., I want to first echo "Cloning repository" and then have the output of git ind...
I've put this script together to updated a folder of forked Github repositories on a daily basis. It runs fine if I call it from a prompt, but I can' figure out how to make it utilize my id_rsa reliably when it is run as a cron job. the eval 'ssh-agent' is an attempt to do just that, but it doesn't seen to have any positive affect. #!/b...
I've taken over supporting a time- and expense-entry system. Apache's CGI. CGI programs are written in bash :) I'm going to add some features into it and exposing it out to many more users, but prior to that wanted to get some thoughts on what else needs to be looked-at first in terms of security, holes, CGI gotchas, &c. Not a lot of...
