I need to remove the 5 digits after the first "_". The new file name should be:
ABC_197_20130708_203556.95336
I'm not quite sure how to do this.
There are lots of ways to do things like this depending on what system you're using and what shell you're using. So, what OS and shell are you using?
And, you need to explain more clearly what you want to do. If you remove the 5 digits after the first underscore from
ABC_2013186197_20130708_203556.95336, I would expected to get
ABC_86197_20130708_203556.95336; not
ABC_197_20130708_203556.95336???

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.
