$ >  echo ${STRING##*_}

$ >  DIR=/home/user1/test
$ > echo ${DIR##*/}

NAME
rushlast - retrieve information of previous uses of rush SYNOPSIS
rushlast [-F STRING] [-f DIR] [-n NUM] [--forward] [-H] rushlast {-v | -h | --usage} DESCRIPTION
rushlast is a utility to search backwards in the session history that GNU rush maintains about all users calling on its services. OPTIONS
-F STRING | --format=STRING Use specified format string instead of the default string. -f DIR | --file=DIR Use database directory DIR. Default location is /var/lib/rush. --forward Display entries in chronological instead of reverse time order. The latter is the default mode of operation. -n NUM | --count=NUM | -NUM Show at most NUM records. The numerical form '-NUM' is to provide compatibility with the standard utility last(1). -H | --no-header Suppress the header line in printout. -v | --version Display program version. -h | --help Display a short help message. --usage Display a concise usage summary. SEE ALSO
The full documentation for rushlast is maintained as a Texinfo manual. If the info and rush programs are properly installed at your site, the command info rush should give you access to the complete manual. See also rush(8) and rushwho(1). AUTHOR
This text was written by Mats Erik Andersson for the Debian project, since the original source supplies a documentation only in the form of a GNU Texinfo manual. GNU Rush 1.7 December 2010 RUSHLAST(1)
