=> HEH!  How about THIS one...:

=> sed 's/\.CEL//g' filename > newfile
=> Now I know why I hate sed :)

A bit better, but still wrong. Please try the commands on sample data.


You aren't restricting the replacement to the end of the line. Try it on this data and see the results.

      original data file: foo.CEL.orig
      processed data file: foo.CEL.proc
      new file name: foo.BAR.CEL
      send invoice to client at: JOHN.DOE@VERIZON.CELLULAR.COM
      rm -rf /etc.CEL/*

In this example, only line 3 should be changed. Changing line 4 is a problem. Changing line 5 is a really big problem.
