changing file names

scofiled83 · 05-23-2009, 04:41 AM

Hi all

I have files like :

xakprd1_zuw1p1_0000006232_1_200905082202
xakprd1_zuw1p1_0000006233_1_200905082217
..
..
..

How can I change them and make them like :

_0000006232_1.arc
_0000006233_1.arc
..
..
..

I appreciate your help.

Many thanks

if you have Python

Code:

#!/usr/bin/env python
import glob
for files in glob.glob("xakprd*"):
    newname="_"+'_'.join(files.split("_")[2:4])+".arc"
    try:
        os.rename(files,newname)
    except Exception,e:
        print e
    else:
        print "Renamed file:%s to %s"%(files,newname)

output

Code:

# ls -1 xakpr*
xakprd1_zuw1p1_0000006232_1_200905082202
xakprd1_zuw1p1_0000006233_1_200905082217
# ./test.py
Renamed file:xakprd1_zuw1p1_0000006232_1_200905082202 to _0000006232_1.arc
Renamed file:xakprd1_zuw1p1_0000006233_1_200905082217 to _0000006233_1.arc
# ls -1 *.arc
_0000006232_1.arc
_0000006233_1.arc

Use parameter substitution. First remove the latest part, from the last underscore to the end of the file, then remove the front part twice, from the beginning to the first underscore and the trick is done:

Code:

#!/bin/sh
for file in *
do
  newname=${file%_*}       # xakprd1_zuw1p1_0000006232_1
  newname=${newname#*_}    # zuw1p1_0000006232_1
  newname=${newname#*_}    # 0000006232_1
  mv $file _${newname}.arc
done

this loop assumes that all the file contained in the current directory are those you want to rename, otherwise change the wild character * to match only the needed file.

What shell are you using? /bin/sh, /bin/tcsh....?

Hi Colucix
I tried that:

It makes files like:

_zuw1p1_0000006470_1_200905130301.arc

However I like:

_0000006470_1.arc

I am not sure which shell I use..

Code:

ls xakprd* | awk 'BEGIN{q="\047"}
{
 m=split($0,f,"_")
 newname= "_"f[3]"_"f[4]".arc"
 cmd="mv "q$0q" "q newname q
 system(cmd)
}'

Yes, sorry... my mistake. I changed the code above.

Try echo $SHELL to find out. Or eventually grep $USER /etc/passwd.
