the probl is that extra ex., you can do it in a 3 steps sed:
Code:
#!/bin/sh OLD=dat TMP=+++ NEW=.dml for old in *.$OLD do new=`echo $old|sed "s/\.$OLD/$TMP/;s/^.*\.//;s/$TMP/$NEW/"` echo mv $old $new done delete 'echo' before 'mv' to make it sharp

not really, yes i forgot the $
try: new=`echo $old|sed "s/\.$OLD$/$TMP/;s/^.*\.//;s/$TMP/$NEW/"` tmp.dat.dat becomes dat.dml OK: tmp.dat.dat.dat.dat will also become dat.dml if rules are not clear, do it by hand, no other choice. sure to do it the right way, you should check the new file name ..... so i would use an other tool, c || perl will be better! the Q here is: isole .dat at end of string, then purge .*\. at begin, finally replace the replaced .dat ex. abc.dat # here you get troubles cde.dat # no probls here: s/dat$/xxx/ the 2.nd Q is: the generic code Last edited by guggach : September 23rd, 2004 at 02:37 AM.
