Using awk or sed to change file names in batch mode

[ericdlester]

I need to change the names of files in a directory in batch mode. i.e. I need to remove all '_' characters in the filenames and maintain the integrity of the files? I have done this previously using sed and/or awk, but it was some time ago. Can someone point me in the right direction? Thank you.

Here is one way using shell and awk together.

It renames files like these:

file1_0_1_2
file2_1
file3
file4_3

into:

file1012
file21
file3
file43

by substituting the "_" for null ("&quot and then renaming
with the mv command.

Test by running as is and if this is what you need, then,
uncomment the mv command and comment out the echo command.


#!/usr/bin/sh

for file in *
do
newfile=`echo $file | nawk '{ gsub("_","&quot ; print }'`
echo $newfile
# mv -f $file $newfile
done


Hope this helps!
