[opensuse] BASH - easiest way to edit/change a single line in multiple files
Listmates, I haven't been able to find an easy way to make edits to multiple files from the command line without doing: (sed or tr) -> tmpfile -> mv tmpfile original file. What I'm looking for is a fast way to for is a fast way to edit an existing file directly and change one or two parameter. An example would be to edit all files in /etc/zypp/repo.d and change the keeppackages=0 to keeppackages=1 or something similar without having to use the copy and move, or having to edit the files one by one. Is there a way to do it? -- David C.

sed -i will edit the file infile directly without the need of tmpfiles, would that be good enough? -- Mads Martin Joergensen, http://mmj.dk "Why make things difficult, when it is possible to make them cryptic and totally illogical, with just a little bit more effort?" -- A.

Hi,
I haven't been able to find an easy way to make edits to multiple files from the command line without doing:
(sed or tr) -> tmpfile -> mv tmpfile original file.
There is a perl prog called "treesed" written by Rick Jansen in 1996 that is very handy for this sort of thing. I should think its still lurking out there somewhere.

Thanks Bogdan, Mads and Tony! I guess I spent so much time focusing on learning the regex aspect of sed that I completely overlooked the -i option. The -i option is great. Tony thanks for the heads-up on treesed. It is a great example script for many aspects of peal. For those interested, the current link for treesed is: http://www.sfr-fresh.com/unix/misc/treesed -- David C.

perl -p -i -e 's/keeppackages=0/keeppackages=1/' FILENAMES You can get backups, by specifying an extension after '-i' (see perldoc perlrun for details). -dnh -- Sigmentation fault. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
