fdiff is a 'filtered diff'. Given a text filter and two inputs, will run the filter across the input files and diff the output.
Fdiff will run the command given by the first argument against the input files given as the second and third arguments, and diff the results. It will use 'diff' as the default diff program, but this can be changed by setting $DIFFCMD, e.g. $ export DIFFCMD=vimdiff; $ fdiff zcat 0716_0020005.raw.gz 0716_0030005.raw.gz ... This function will work under bash, but requires the use of command substitution, which is not available under a strict ANSI shell.
