A loop should do (in a POSIX-like shell):
for f in *.bak; do
mv -- "$f" "${f%.*}"
done
And as one line:
for f in *.bak; do mv -- "$f" "${f%.*}"; done
Use rename command:
rename 's/\.bak$//' *.bak
's/\.bak$//'- perl expression to match all filenames ending with.bakand strip the extension

@yode, try
prename 's/\.bak$//' *.bak(Perl version)RomanPerekhrest– RomanPerekhrest2017-06-23 14:17:28 +00:00Commented Jun 23, 2017 at 14:17 -
It's seem
rename .bak '' *.bakwork for this..yode– yode2017-06-23 14:23:52 +00:00Commented Jun 23, 2017 at 14:23 -
it seems that you are using another implementation, see this post unix.stackexchange.com/questions/78621/…RomanPerekhrest– RomanPerekhrest2017-06-23 14:25:45 +00:00Commented Jun 23, 2017 at 14:25
Something that should work across all platforms:
for i in *.bak
do
mv $i `echo $i | sed 's/\.bak$//'`
done
-
You need quotes around
$iand the command substitution to deal with whitespace in filenames. (Some newlines would still cause somewhat odd results.)ilkkachu– ilkkachu2017-06-23 15:23:19 +00:00Commented Jun 23, 2017 at 15:23
As the promp of RomanPerekhrest's answer here,I find this command work for me.
rename .bak '' *.bak

Note that it would rename
best.baker.baktobester.bakand would choke on file names that start with-.Stéphane Chazelas– Stéphane Chazelas2017-06-23 14:35:18 +00:00Commented Jun 23, 2017 at 14:35
#!/bin/bash
for val in \`ls *.bat`
do
mv $val `echo $val | cut -f1 -d'.'`
done

That makes a lot of assumptions, like that none of the bat files are of type directory, that their names don't contain space, tab, newline,
*,?,[backslash characters, that they don't start with-, that they contain no other.characters.Stéphane Chazelas– Stéphane Chazelas2017-06-23 14:39:50 +00:00Commented Jun 23, 2017 at 14:39 -
The
lshere doesn't do anything (but cause issues), the shell still generates the list of file names. See also: mywiki.wooledge.org/BashPitfalls#for_i_in_.24.28ls_.2A.mp3.29ilkkachu– ilkkachu2017-06-23 15:25:37 +00:00Commented Jun 23, 2017 at 15:25
