+# Last Change: 17-Mar-2004 @ 18:47\r
+# Requires:\r
+# - bash or ksh (tested on cygwin and MKS respectively).\r
+# - Info Zip for the -z option to work (comes with linux/cygwin). Download for\r
+# free from:\r
+# http://www.info-zip.org/\r
+# - GNU tar for the -a option to work (comes with linux/cygwin).\r

+# Description:\r
+# Shell script to take backup of all the open files in perforce SCM.\r
+#\r
+#TODO:\r
+# - Zip comment option -zz is no longer working?\r
+# - To create cpio archives, I can use "cpio -o -H | gzip" command.\r
+# - Option to generate a diff at the end.\r
+# - Option to restrict by type (useful to avoid huge binary files).\r
+# - Support to run zip from a different directory (to avoid certain path\r
+# component from getting into zipfile).\r

+$0 [<backup dir>] [<source dir>] ...\r
+$0 -h -n -q -v -z -zz [-c <change number>] [-t <backup dir>] [-r <backup root>] [[-s <source dir>] ...]\r
+ -t specify full path name to the target directory. If -z is specified this\r
+ becomes the path to the zip file name.\r
+ -r set the root for creating the default backup dir/zip file. Not used if\r
+ "backup dir" is specified. You can also set BAKUP_ROOT environmental\r
+ variable. Defaults to p: (p drive), because that is what it is on my\r
+ system :).\r
+ -i incremental backup, which makes the program use the previous backup\r
+ directory/archive for that day (if it exists) instead of creating a new\r
+ one. For tar (with "-a" option), you will have to provide one of the\r
+ relevant options to force reuse an existing archive ("-ar" e.g.) or the\r
+ existing archive will simply get overwritten. However this will not work\r
+ with compressed tar archives. You can also specify any existing backup\r
+ directory/archive path explicitly by using the "-t" option.\r
+ -a create a tar file instead of copying the files. You can specify the\r
+ tar file name using -t option.\r
+ -a[-|--]<taropt>\r
+ Pass -taropt to tar command.\r
+ Ex:\r
+ - Pass "-aC <dir>" or "-adirectory=<dir>" to cd to a directory before\r
+ creating the tar file (thus dropping file component).\r
+ - Pass "-az" to gzip the created tar file.\r
+ -z create a zip file instead of copying the files. You can specify the\r
+ zip file name using -t option.\r
+ -z[-]<zipopt>\r
+ Pass -zipopt to zip command.\r
+ Ex: Pass -zz for a prompt from zip to enter a comment.\r
+ -s limit to open files matching the given wildcard (local or depot). This\r
+ can be repeated multiple times to specify multiple source directories.\r
+ You can pass in anything that the 'p4 opened' command itself accepts.\r
+ -c limit the files to those specified in the change number, in addition to\r
+ the -s option. This can't be repeated multiple times though.\r
+ -n don't execute any commands, just show what is going to be done. Does not\r
+ currently work with -z option.\r
+ -q quite mode, no messages\r
+ -v verbose mode, print messages (the default).\r
+ -h print help message (this message) and exit\r
+ The first unspecified directory is treated as target directory, and the\r
+ remaining directories are treated as source directories. The '-n' option can\r
+ be used to generate a batch script that can be run later. The source\r
+ directory can be in depot or local format (NO BACKSLASHES PLEASE). Do not\r
+ combine multiple options into one argument.\r
+Examples:\r
+ bakup.sh\r
+ - Backup all the open files into a default generated backup dir. in p:\r
+ drive (p: driver is the default backup directory).\r
+ bakup.sh mybak c:/dev/branch/src\r
+ - Backup open files only under 'c:/dev/branch/src' into 'mybak'\r
+ directory.\r
+ bakup.sh -s //depot/branch/src -s //depot/branch/cfg\r
+ - Backup open files only under 'src' and 'cfg' into the default bakup\r
+ dir.\r
+\r
+ You could add -z option to all the above usages to create a zip file\r
+ instead of creating a directory. You need to have Info-Zip installed in the\r
+ path for this to work.\r
+\r
+ bakup.sh -n > mybackup.bat\r
+ - Generates a 'mybackup.bat' batch file that can be run at a later\r
+ time to take a backup. The files to be backed up are based on the\r
+ time the script was generated, so it should be regenerated if the\r
+ list has changed since then.\r
