Re^6: changing date format in and out

The $_ in localtime $_ is not optional: without it, the function returns current local time; likewise gmtime().

The -l (that's a small ell) command line switch may be useful: it will automatically chomp the input record separator (IRS) on input and append the ORS on output. (IRS and ORS are both a newline by default.) As mentioned, not so important on input, but on output this gives you your converted time strings each on a separate line rather than as one (very long) line.

Example without -l command line switch:

>perl -wMstrict -ne "print scalar localtime $_"  < utimes  > ltimes

I replaced gmtime with localtime and it seems to work properly. Thanks Any advice anyway?
