BASH - Remove string from filename-CodePudding

I'm trying to remove some strings from filenames i have in a directory using bash. I've tried the following with no success.

rename --version

rename from util-linux 2.23.2

rename -v 's/[.].*//' *

rename -v 's/\.vesta-01:2,//' *

Original File Name(s):

1667874526.M308257P1693.vesta-01:2,

1667883117.M371701P32232.vesta-01:2,

Desired File Name(s):

1667874526

1667883117

CodePudding user response：

rename from util-linux doesn't accept Perl substitution. See man 1 rename:

rename [options] expression replacement file...

You can use mv in a loop with parameter expansion instead:

for f in *.vesta-01:2, ; do
    mv "$f" "${f%%.*}"
done

CodePudding user response：

Try using mv with bash parameter expansion instead:

$ ls 166*
1667874526.M308257P1693.vesta-01:2  1667883117.M371701P32232.vesta-01:2
$ f1="1667874526.M308257P1693.vesta-01:2" ; mv "$f1" "${f1%%.*}"
$ f2="1667883117.M371701P32232.vesta-01:2" ; mv "$f2" "${f2%%.*}"
$ ls 166*
1667874526 1667883117
