Hi, Could anyone give me some help with some bash scripting. I'm trying to write a script for an hourly back up but I don't know how to add a timestamp in to the tar output file name. What I have currently (with confidential parts hidden) is: #!/bin/bash su _USER_ -c "cd /home/_USER_; tar -czf _NFSMOUNT_/_FILENAME_._COMPUTERNAME_._DATE_.tar.gz _DIRECTORYTOBU_/" Anything with _TEXT_ is the ommitted text except for the _DATE_. Anyone please?
