Retain File Timestamp
There are directories of files that I have to run the dos2ux command on to get ride of the carriage return characters. Easy enough, but I have to retain the original timestamps on the files. I am thinking that I am going to have to strip off the timestamp for each file and convert it to unix time and then run touch against each file after recreating the file with dos2ux. This is probably as clear as mud, but does anyone have any elegant ideas for accomplishing this?
I am planning to loop through the listing but my elegance lags when I try am trying to figure out the best way to do the conversion. Or am I missing some tool available on HP-UX that will not alter the timestamp but will remove the ^M from the end of every line? Thanks in advance.

pam_timestamp_check
pam_timestamp_check(8) System Administrator's Manual pam_timestamp_check(8)
NAME
pam_timestamp_check - check or clear authentication timestamps
SYNOPSIS
pam_timestamp [[-d]|[-k]] [target_user]
DESCRIPTION
With no arguments, pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it.
OPTIONS
-k instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option.
-d Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output.
target_user
The default behavior of pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as
herself. When the user authenticates as a different user, the name of the timestamp file changes to accomodate this.
DIAGNOSTICS
When checking if a timestamp is valid, pam_timestamp_check returns an exit code of 0 for success and > 0 on error:
2: binary is not setuid-root
3: invalid invocation
4: user unknown
5: permissions error
6: invalid controlling tty
7: other error

BUGS
Let's hope not, but if you find any, please email the author.
