I have a string "\/scratch\/databases\". I want

Please help me.

You must use a \ in front of the \ to make it a \\ in your search and replace functions because of the special nature (meta) of the \ char. Example in vi editor:

Code:

:%s/\\$//

The fragment above says "search for the \ at the end of a line and replace with nothing"

Note. that I've not tested the fragment above and it might need some more tweaking to work.

Hello,
Thank you so much for your reply.
I tried
Code:
:%s/\\$// don't replcae '\' character at the end of line
:%s/\\// replace only first '\' character of line
:%s/\\//g replace all '\' characters of line.

I need help.
Thanks in advance

If you want to do it in vi, I would use this:

:g/\\$/s///


Your original post said you are trying to write a shell script. In which case, you could do:

FOO='\/scratch\/databases\'
echo $FOO | sed 's/\\$//'

Thank you so much for your help.
I've got it as follows:
FOO="\/scratch\/databases"
echo $FOO | sed 's/\\$//' > tmp.log
DAEHOME=`cat tmp.log`
I can not use
DAEHOME=`echo $FOO | sed 's/\\$//'`
