zgrep might be handy too (Score:1)

zgrep -v '^ftp.itransact'
Of course once you add in a shell loop to iterate over the files and re-gzip them it starts to look like your original code :-)

  Yeah, true. zgrep's pretty handy for scanning but not so much use for in-place mods, so far as I've seen. I'm sure it's possible with some of bash's more esoteric (for me!) constructs... But why bother when perl's there, heh. It's funny watching these little hacks have perl appear in there somewhere (f=`perl ...`), then as more functionality is needed, more of it gets shoe-horned into the perl invocation until *pop* it's all in perl and it gets re-written "properly":
  
  #!/bin/sh exec perl $0.pl
  
  :-)
