Status and error messages written to console and logfile. Selectable compression level, recursion(y/n), log and dest files selectable via commandline switches. =head1 Requires Archive::Tar http://search.cpan.org/search?dist=Archive-Tar Getopt::Long http://search.cpan.org/search?dist=Getopt-Long Perl http://www.cpan.org/ports/ gzip http://www.gzip.org/ =head1 Tested Archive::Tar 0.22 Getopt::Long 2.25 and 2.19 Time::localtime 1.01 gzip 1.13 Perl 5.00503 Debian 2.2r3 Archive::Tar 0.072 Getopt::Long 2.23 Time::localtime 1.01 gzip 1.2.4 ActivePerl 5.006 MSWin32 5.0 b2195 sp1 Archive::Tar 0.22 Getopt::Long 2.24 Time::localtime 1.01 gzip 1.2.4 Perl 5.006001 Cygwin 1.1.8-1 MSWin32 5.0 b2195 sp1 =head1 Updates 2001-06-04 12:40 Retest on Win32 ActivePerl, and on Cygwin. Add Getopt::Long abreviations to Usage(). '--recurse' option with no argument. Untaint commandline switches. Usage(). Getopt::Long commandline switches. 2001-06-03 21:40 Post to PerlMonks (Code Catacombs->Utility Scripts). Unsubify 'report versions' since only done once. Test with: Cygwin Win2kPro ActivePerl Win2kPro 2001-06-02 Configurable recursion(y/n) and compression level. Timestamp at start and end of run. Add umask for bit o'security. Print to logfile in addition to console. Depth-first recursion instead of width-first (while+shift+unshift instead of for+push) Display outfile size with 'stat'. Filetest to exclude symlinks. (avoid endless looop on Debian /etc/apache/conf->./) (no read-perm check on purpose, so errmsg on unreadable file(s)) Add "qw" to @dirs and move comment out of parens. 2001-06-01 Directory recursion. Initial working code Debian 2.2r3 =head1 Todos Archive::Zip, File::Find, or File::Recurse instead of hand-rolled rec +ursion. Good regex instead of blind untaint outfile and logfile from commandl +ine. --nolog option where $file{log} = '/dev/null'. Reduce untaint redundancy. Reduce TimeStamp() redundancy. Make logfile 'live'. Add $version reporting. =head1 Author ybiC =head1 Credits Thanks to: Vynce, mlong, bikeNomad, zdog, and Beatnik for recursion suggestion +s, Petruchio for assorted tips, clintp for sane way to add elts to list while looping through same +list, DrZaius for slick Getopt::Long pointers, Oh yeah, and some guy named vroom, too. =head1 Sample logfile of tgz.pl -r -c 9 Launching tgz.pl 2001- 6- 4 3:41:46 Read directories and files /var/www /var/www/HOWTO.ps /var/www/Webalizer /etc /etc/apache /etc/Net /etc/imlib /etc/logrotate.d /etc/cron.d /etc/cron.monthly /etc/rcS.d /etc/rc6.d /etc/rc5.d /etc/rc4.d /etc/rc3.d /etc/rc2.d /etc/rc1.d /etc/rc0.d /etc/rc.boot /etc/cron.weekly /etc/chatscripts Error opening /etc/chatscripts: Permission denied Error reading /etc/chatscripts: Permission denied Error closing /etc/chatscripts: Permission denied /etc/ppp Error opening /etc/ppp: Permission denied Error reading /etc/ppp: Permission denied Error closing /etc/ppp: Permission denied /etc/network /etc/cron.daily /etc/default /etc/apt /etc/init.d Write and compress tgzball /home/me/tgzpl.tar.gz 25293464 bytes tgz.pl finished. 2001- 6- 4 3:43:11 =cut
