MD5-Hash - dirtree_md5.pl
The LoxBerry script dirtree_md5.pl creates md5 hashes of single files or of a full directory tree. It also can compare the md5 with a given md5 string.
Calling
$LBSBIN/dirtree_md5.pl <parameters>
(usually /opt/loxberry/bin/dirtree_md5.pl)
Parameters
| Parameter | Usage |
|---|---|
| -path <dirpath> | Checks the complete directory tree. A tree is only "equal" if all files have the same md5, and also the number of files is equal (no more or less files) |
| -file <filepath> | Checks a single file |
| -compare <md5> | Compares the result of -file/-path with the given md5. Returns 0 if equal, or 1 if NOT equal. |
| -v / -verbose | Activate verbosity. Gives lists of files and md5's |
