Hi all,

I am a newbie in writng unix..I am using ksh shell..Does anyone know how to copy a list o files from directory A to directory B with differnt names? i.e
in Dir A, I have
RPT101.555.TXT
RPT102.666.TXT

and I want to copy those files to dir B with new naming convention..
in Dir B, I wanna have those files names

RPT.101.555.20050225163012.TXT
RPT.102.666.20050225163013.TXT
...

where 20050225163012 is infact the timestamp when I copy those files
format is yyyymmddHHmmss

I try to use comand sed ..but I am in big mess right now..

please help.. Thx~!

You posted two different file output in this post - wasn't sure which is correct.
Input file should be RPT101 or RPT.101 - script below assumes RPT101 - just add 'cutting' another field if that incorrect.

Code:

#!/bin/ksh
files=`ls -1 RPT*.TXT`
for xx in $files
do
    newname=`echo $xx|cut -d. -f1,2`
    now=`date '+%Y%m%d%H%M%S'`
    cp $xx ./junk/$newname.$now.TXT
done

Just change or add any specific directory path - should work if I understood what you are looking for.

Here's one that'll work regardless of which input filename format (RPT101.*.TXT or RPT.101.*.TXT) is used....

Code:

$ cd /dirA
$ ls -1 *.TXT
RPT.102.666.TXT
RPT101.555.TXT
$ cat > rename.ksh
#!/bin/ksh

ls *.TXT | while read file
do
  cp "$file" /dirB/${file%.*}.`date '+%Y%m%d%H%M%S'`.TXT
done
^D
$ chmod +x ./rename.ksh
$ ./rename.ksh
$ ls -1 /dirB/*.TXT
RPT.102.666.20050226024347.TXT
RPT101.555.20050226024347.TXT

Thx for all reply first. To be more specific, this is my data..

SSSBR101R01A123.D20041224.TXT

I want to copy this file to another directory with a new name

SSSBR101.R01.A123.RPTDUMMY.D20041224.20040226.183033.BIN
|________|
This is the current date and time yyyymmdd.HHmmss

=========================
converning the solution given above.. I try the follwing and put the news files in teh same dir after renaming and simpfy the rename convention..but I got this error when I try to run the script..

[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt: ls
SFSBR101R01I123.D20050131.TXT SFSBR101R01ITLS.D20050131.TXT

#! /bin/sh

ls *.TXT | while read file
do
cp "$file" ${file%.*}.`date '+%Y%m%d%H%M%S'`.TXT
done
^D[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt: ls -l rename.ksh

[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt: rename.ksh
ksh: rename.ksh: not found
[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt:

why?

The current directory is not included in your path - invoke the script with

./rename.ksh

ZB,

thx for yr reply but same problem even I re-run it like following,

[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt: ls
SFSBR101R01I123.D20050131.TXT SFSBR101R01ITLS.D20050131.TXT
SFSBR101R01IABF.D20050131.TXT rename.ksh
[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt: ./rename.ksh
ksh: ./rename.ksh: not found
[devuser]/project/sfs/ostdev/ftp/snd/ondemand/rpt_txt:

For a start, make sure that you change the shebang line to
#!/bin/ksh
as there are korn shell specific builtins used....

Also, remove the ^D from the end of the script - that was in my output because I scripted on the fly redirecting cat to a file....

Try doing

ls -lb .

to check that no non-printing characters have been put into the rename.ksh filename as you entered it in.... if you see some octals in there - that's the culprit....

Let us know if that makes any difference.
