You should use caution with the grep command. You may not get exactly the results you expect.
Code:
jack@veritron ~ $ cat t3
abc.txt
1abc.txt
abc.txt1
jack@veritron ~ $ grep abc.txt t3
abc.txt
1abc.txt
abc.txt1
jack@veritron ~ $ grep ^abc.txt$ t3
abc.txt
jack@veritron ~ $

RMM(1)								     [nmh-1.5]								    RMM(1)

NAME
rmm - remove messages SYNOPSIS
rmm [+folder] [msgs] [-unlink | -nounlink] [-version] [-help] DESCRIPTION
By default, rmm will remove the specified messages by renaming each of the message files with a site-dependent prefix (usually a comma). Such files will then need to be removed in some manner after a certain amount of time. Many sites arrange for cron to remove these files once a day, so check with your system administrator. Alternately, if you wish for rmm to really remove the files representing these messages, you can use the -unlink switch. But messages removed by this method cannot be later recovered. If you prefer a more sophisticated method of `removing' messages, you can define the rmmproc profile component. For example, you can add a profile component such as rmmproc: /home/foouser/bin/rmm_msgs then instead of simply renaming the message file, rmm will call the named program or script to handle the files that represent the messages to be deleted. Some users of csh prefer the following: alias rmm 'refile +d' where folder `+d' is a folder for deleted messages, and alias mexp 'rm `mhpath +d all`' is used to "expunge" deleted messages. The current message is not changed by rmm, so a next will advance to the next message in the folder as expected. FILES
$HOME/.mh_profile The user profile PROFILE COMPONENTS
Path: To determine the user's nmh directory Current-Folder: To find the default current folder rmmproc: Program to delete the message SEE ALSO
refile(1), rmf(1) DEFAULTS
`+folder' defaults to the current folder `msgs' defaults to cur `-nounlink' CONTEXT
If a folder is given, it will become the current folder. BUGS
Since refile uses your rmmproc to delete the message, the rmmproc must NOT call refile without specifying -normmproc, or you will create an infinte loop. MH.6.8 11 June 2012 RMM(1)
