tr is not really using regular expression. It just replaces/deletes characters from the string. Also you can't really combine this expressions into single "tr" or even single "s///" as you are checking the number of different characters removed.

i-ls(1) 						      General Commands Manual							   i-ls(1)

NAME
i-ls - display file stat and checksum information for files SYNOPSIS
i-ls [-s] filename i-ls [-s] dirname Specify a filename for i-ls to examine, or specify a directory with dirname to examine all the files in the directory. -s Do not show/calculate checksums for all regular files. DESCRIPTION
The integrit system detects intrusion by detecting when trusted files have been altered. integrit records information about files in a database. i-ls allows the user to see that information for live files. The output syntax is the same as that of integrit. EXAMPLES
i-ls /tmp/foo.txt shows file stat attributes for the file, "/tmp/foo.txt". i-ls /tmp shows file stat attributes for all files in the directory, "/tmp". i-ls -s /tmp shows file stat attributes for all files in the directory, "/tmp", also including also checksums for all regular files. AUTHOR
Ed L Cashin <ecashin@users.sourceforge.net> See the integrit web site for up to date releases and information at http://integrit.sourceforge.net/ SEE ALSO
