How do I edit file name that same first word

Question

I have log files like this:

tmp_1_2_3_4_5.LOG
...

I need to change name like this:

1_2_3_4_5.LOG

I try:

rename 's/^tmp+_//' *

It's working on Debian, but not working on Red Hat. How can I do this with mv command?

Does rename command different on Red Hat? It's working on Debian, but does not on Red Hat. If I can't do this with rename, how can I do this with other command? Sed or mv etc... I need one line command for this. — onur, Nov 11 '14 at 08:05

You can do this with a fairly simple for-loop:

for file in tmp_*; do
    [[ -e $file ]] || continue
    mv "$file" "./${file#tmp_}"
done

You can try this, with mv :

for i in *; do s=$(sed -r 's/^(tmp_)(.*.LOG)/\2/' <<< $i); if [[ "$i" != "$s" ]]; then mv "$i" "$s"; fi; done;

It's working for all files, not just tmp_xxx_xxx.LOG. And said for other files: mv xx_xx.LOG and xx_xx.LOG are the same file. – onur Nov 11 '14 at 08:29
