Replace a character in a variable

[cbsm]

I know how to replace a character in a file (using grep for example).
What I need to do is to replace a character in a variable :
MyVar="abcd/ter/123"
and I need to replace "/" with "_"
(in the end I want MyVar="abcd_ter_123"

It's probably soooooo easy ... but I'm stuck ...

Thank you !!!

Hi

In most modern shells :

MyVar="${MyVar//\//_}"

Feherke.

In less modern shells...

# Ksh
MyVar=$(echo ${MyVar} | sed 's|/|_|g')

# bourne
MyVar=`echo ${MyVar} | sed 's|/|_|g'`
