RedHat Search for / and insert \ for every instance
Hi,

I want to do a sed (linux) or the alternative in PHP to insert a backslash in front of every occurrence of every forward slash

ex.

/archive/data/stanley
-->
\/archive\/data\/stanley

I appreciate it!

Code:
sed 's#\/#\\\/#g'

OR
Code:
sed 's#\/#\\&#g'

If i want to assign post result in shell script as:
assigning the literal string to a variable ..

echo $VERSION | sed 's#\/#\\\/#g' > $MOD_VERSION

What's the way to make that work?

/ is only special when it's used as the delimiter.

The highlighted backslashes are incorrect and produce undefined escape sequences.

POSIX sed:
Quote:
The meaning of a <backslash> immediately followed by any character other than '&', <backslash>, a digit, or the delimiter character used for this command, is unspecified.

You don't need sed for that in bash or ksh:

Code:
VERSION="${VERSION//\//\\/}"

if you are forced to use an old shell:

Code:
VERSION=$(echo "$VERSION" | sed 's#/#\\/#g'
