I am trying to write a bash script that contains a function so when given a .tar, .tar.bz2, .tar.gz etc. file it uses tar with the relevant switches to decompress the file.
I am using if elif then statements which test the filename to see what it ends with and I cannot get it to match using regex metacharacters.
To save constantly rewriting the script I am using ‘test’ at the command line, I thought the statement below should work, I have tried every combination of brackets, quotes and metacharaters possible and still it fails.
test sed-4.2.2.tar.bz2 = tar\.bz2$; echo $?
(this returns 1, false)
I’m sure the problem is a simple one and I’ve looked everywhere, yet I cannot fathom how to do it. Does someone know how I can do this?
