tool to subsitute foo by bar in multiple files

[mezhaka]

hello, ubuntu users!

i have a bunch of python files and i'd like to change the name of a particular variable throughout many files in a particular directory, but i has to be a command line tool. can anyone suggest one? i could have written a perl oneliner for that. but i guess it's a solved problem, i'm just not aware of the solution.

Check out sed.

(I) have a bunch of python filesIt can also be done pretty easily using Python. There are threads in this forum about doing similar things using SED, per the above post, if that is your script of choice.

sed is your friend.....

cat *.py |sed 's/foo/bar/g'

i assume you know Python


import glob,os
yourdir = os.path.join("/","test")
os.chdir(yourdir)
for fi in glob.glob("*foo*.py"):
newfile = fi.replace("foo","bar")
os.rename(fi,newfile)

A decently powerful tool I use when I feel like a gui and more features (like undoing changes - I think...) is KFileReplace, available through synaptic.

EDIT - sorry missed that it has to be command line.

sed -i -e 's/foo/bar/g' *.py

tomchuk,

I'm embarrassed by how long I've been trying to sort that out.

Thank you.
