Jim,

We have an exact requirement, but it is not like chj's where it is on two different mountpoints. The files are on one directory and one mount point. All we need to do is update the timestamp of the file so they don't automatically get purged due to aging by our retention policy.

I used the exact code for the same requirement...but it does not work. We have AIX box and use ksh shell. I believe it is due to that...

Instead I was trying to use it this way. It does change the timestamp, but I would like to pass the timestamp as a parameter like you suggested
Code:
(+%Y%m%d%H%M%S)

so when we run this on a monthly basis it will change the timestamp as of the run date.

Code:
#!/usr/bin/ksh
find . -type f |
while read fname
do
touch -t 201003050525.26 $SEQ_DIR/${fname}
done

In additon to that, how can we also make the code work so it only picks the files that we need? Should we pass a list file as a parameter which has the list of files that need to be touched with the new timestamp?

Please advise on the best way to approach this.

Regards,
MK

SHAR(1) 						    BSD General Commands Manual 						   SHAR(1)

NAME
shar -- create a shell archive of files SYNOPSIS
shar file ... DESCRIPTION
shar writes an sh(1) shell script to the standard output which will recreate the file hierarchy specified by the command line operands. Directories will be recreated and must be specified before the files they contain (the find(1) utility does this correctly). shar is normally used for distributing files by ftp(1) or mail(1). SEE ALSO
compress(1), mail(1), uuencode(1), tar(1) BUGS
shar makes no provisions for special types of files or files containing magic characters. EXAMPLES
To create a shell archive of the program ls(1) and mail it to Rick: cd ls shar `find . -print` | mail -s "ls source" rick To recreate the program directory: mkdir ls cd ls ... <delete header lines and examine mailed archive> ... sh archive HISTORY
The shar command appears in 4.4BSD. SECURITY CONSIDERATIONS
It is easy to insert trojan horses into shar files. It is strongly recommended that all shell archive files be examined before running them through sh(1). Archives produced using this implementation of shar may be easily examined with the command: egrep -v '^[X#]' shar.file 4.4BSD June 6, 1993 4.4BSD
