touch -m -d "date" filename
But 'touch' command under Mac OS X has different parameters and after using the same command we will get error:
touch: illegal option -- d
usage: touch [-acfm] [-r file] [-t [[CC]YY]MMDDhhmm[.SS]] file
So to have this task done we had to write check for Mac OS and Linux platforms and pass different parameters to 'touch' command depending on OS.
To resolve this issue simple Perl script was written:
#!/usr/bin/perl
if (@ARGV[0] eq '' || @ARGV[1] eq '') {
print "Change file modification date.\n";
print "Usage: perl_touch.pl timestamp filename\n";
exit;
}
utime undef, @ARGV[0], @ARGV[1];
First param - unix timestamp, second - filename. Scripts works under both - Mac OS X and Linux.
