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

RBASH(1)						      General Commands Manual							  RBASH(1)

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
