Ubuntu8.04 the next script to replace rm

Ubuntu8.04 always brings me a lot of trouble, and this LSV is no exception. every two months, scim-launcher will load continuously until it is full of memory and swap. This time it is too late to run gnome-system-monitor (gnome-terminal is not to be mentioned, it is slower, it is too late ). Last time I created a new user yuanmm and login, backed up yuangg, copied the configuration file, and logged in to tune the font for half a day.

Ubuntu 8.04 always brings me a lot of trouble, and this LSV is no exception. every two months, scim-launcher will load continuously until it is full of memory and swap. It is too late to run gnome-system-monitor ). The last time I created a new user yuanmm and login, backed up yuangg, copied the configuration file, and logged in to tune the font for half a day. In case of protection, I also set the adjusted configuration file tar-vczf p2.tar.gz/home/yuanmm/. [a-zA-Z. It was used.

However, in the repeated chown/mv/cp/rm, accidentally deleted a. * folder that took a lot of time to collect. This is the second time. Last deleted *~ When the number of attacks is less ~, Who said CL is not prone to errors ?! The key is hard to recover ...... I decided to write a script to replace rm.

I used to think that shell programming is quite weak and difficult to read. I forgot everything when I learned high skills. As a result, I stayed up late last night and was late in the morning. I scanned the shell programming I had previously learned. I would like to share with you. Dos seems to have del commands, so my script is named del and placed in ~ /Sbin, and then

Chmod a + x ~ /Sbin/del, ln-s ~ /Sbin/*/usr/local/sbin.

#! /Bin/sh
If [! -D $ HOME/. trash]
Then mkdir $ HOME/. trash
Fi
If [$ LOGNAME = "root"]
# Then delBy = "$ LOGNAME @ $ USERNAME"
# Else delBy = "$ USERNAME"
Then delBy = ": $ USERNAME"
Fi

For toDel
Do
Backup = $ HOME/. trash/'basename $ toDel '$ delBy
Nsec = 'date + % N'
# Msec =$ {nsec: 0: 3}
If [! -F $ backup-! -D $ backup]
Then mv $ toDel $ backup
# Else mv $ toDel $ backup: $ msec
Else
Mv $ toDel $ backup: $ nsec
Touch-a $ backup: $ nsec
Fi
Done

I don't know why $ {nsec: 0: 3} cannot run normally. It can be used in command lines. Here, neither can 'echo $ {nsec: 0: 3. So I had to discard the msec timestamp. I want the final version to retain the information of the location to be deleted (for example, move tmp ~ /. Trash/tmp@home.yuangg: root @ yuangg: 616), and then write a udel to restore the deleted file. However, if the substring uses awk or sed, it will be out of the scope of the high operation. Wait for the idle time.
