Is there any way I could use grep to ignore some files when searching something, something equivalent to svnignore or gitignore? I usually use something like this when searching source code. grep -r something * | grep -v ignore_file1 | grep -v ignore_file2 Even if I could set up an alias to grep to ignore these files would be good. ...
Sorry I'm new to this sort of thing. I'm trying to write a bash script that uploads a file to a server. How can I achieve this? Is a bash script the right thing to use for this? Solution: I ended up using scp to copy the files securely. scp <file to upload> <username>@<hostname>:<destination path> I also set up public key authentica...

How can ssh from within a bash script? ...

For my use it doesn't actually need to be a ...
Bash lets you complete commands names and names of files in the arguments with the TAB key. But why not also common options to commands? Why not, even better, a completion system that tells you what an option does, too? I heard of programmable completion.. but don't understand where it fits.. So my question is: is there a way to achiev...
I just want to match some text in a BASH script, i’v tried using sed, but I can’t seem to make it just output the match instead of replacing it with something. echo -E "TestT100String" | sed 's/[0-9]+/dontReplace/g' Which will output: TestTdontReplaceString Which isn’t what I want, I want it to output: 100 Ideally I would want it to...
How do I check a int variable ($inputNo) to see if it’s 2 or more decimal digits long? Example: inputNo="5" Should be changed to: 05 inputNo="102" Should be left alone: 102 I thought about using wc and if statements, but wc -m doesn’t seems to give the actual characters passed into wc, as wc always seems to give +1 to the charact...
Hi all, I have a bash script that I am run to check to see if one of my programs has hung, and if it has kill it. The script works fine if ran from the command line, but if I schedule it with cron it does something very strange. Basically the script (below) gets the PID of my program and gets its created date/time from its entry in the ...

Hello, I'm attempting to write a bash routine that tests whether or not a user's input is the correct password to my certificate database. Originally I imagined I'd first execute a benign certutil or pk12util operation on the certificate database that required a password. Then test the return code to see if it was successful. However,...

How to make locale aware uppercase operation? Standard tr '[:lower:]' '[:upper:]' trick doesn't work: =$ echo żółw | tr "[:lower:]" "[:upper:]" żółW (it should be ŻÓŁW) I'd rather avoid having to run Perl or anything such heavy-weight. ...
How can I spawn a process after a delay in a shell script? I want a command to start 60 seconds after the script starts, but I want to keep running the rest of the script without waiting 60 seconds first. Here's the idea: #!/bin/sh # Echo A 60 seconds later, but without blocking the rest of the script sleep 60 && echo "A" echo "B" echo...

It only goes one level deep. How can I make it step through all directori...
