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.
