The best solution I found so far is: NAME=`echo "$FILE" | cut -d'.' -f1` EXTENSION=`echo "$FILE" | cut -d'.' -f2` This is wrong because it doesn't work if the file name contains multiple . characters. If, let's say, I have a.b.js, it will consider a and b.js, instead of a.b and js. It can be easily done in Python with fil

How to convert timestamps to dates in Bash?
I need a shell command or script that converts a Unix timestamp to a date. The input can come either from the first parameter or from stdin, allowing for the following usage patterns: ts2date 1267619929 and echo 1267619929 | ts2date Both commands should output "Wed Mar 3 13:38:49 2010".
