Shell Programming and Scripting

I have a line that contains backslashes in which I want sed to substitute text with variables.

The line;

\\s008\2033330user$
I want to change this in \\s008.ourschool.com\2033330user$

I now use this script:

USER=2033330user
sed 's/\\'"$USER"'/.ourschool.com\\'"$USER/"

This doesn't seem te work for me. What am I doing wrong?

The double backslash is to protect a single one from being interpreted as a special character by the shell, but I believe that enclosing a single one in single quotes will have the same effect, so try

Code:

USER=2033330user
sed 's/\'"$USER"'/.ourschool.com\'"$USER/"

or stick with double backslashes and enclose the whole lot in double quotes

Code:

USER=2033330user
sed "s/\\$USER/.ourschool.com\\$USER/"

Thank you for replying.

If I use your suggestion, the end result is slightly different from what I want. I now get this output:
.ourschool.com\\s008\2033330user
This happens with both your suggestions.

I want this output:
\\s008.ourschool.com\2033330user

Even so, if I use an input with a $, sed doesn't change anything. For example, one of our users has a home directory on \\s008\2033330user$

If I use the sed script, sed gives the same output as the input. It doesn't change the input. Does sed interpret this dollar sign as a special character?

Thank you for time!

Have a similar problem that I'd HUGELY appreciate help with.

I've got a trojan that put one very large line of code into hundreds of files on my server. Its full of back slashes, forward slashes etc.

Is there any quick way of saying:

DELTE THIS LINE IF ITS GOT "<?php if(!function_exists('tmp_lkojfghx')){if(isset" in it?

Im using sed to replace characters with blanks
