Theres no undelete command in Unix. However, i can think of 2 ways u
cud handle deletion.
1. Set an alias as rm -i in your .profile so that whenever any file is
deleted, u will be prompted for confirmation.
[ alias rm 'rm -i'; ]
2. Shell scripts :
- Write a shell script that will copy the file being deleted in a
different folder and then deletes it from the source folder.
- Set rm as alias for running this script
- Create another shell script that reads the mentioned file from
backup folder and moves it to the current folder.
- Give this shell script an alias (say undelete)
There are some utilities you can purchase that claim to recover deleted files
but I do not know how affective they are.

Hi,
I'm writing a post-upgrade script and I want to find which files don't have read and execute to everyone.
I can run a find . ! -perm, but then I have to use a list of the possible permissions (777,775, 755 etc). Is there a more elegant solution?
Thanks (2 Replies)

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.
