Code:
b=${a/23/BB}

this works on variable "a" and replaces "23" with "BB".

Code:
root@OpenWrt:~# a=1234
root@OpenWrt:~# echo ${a/23/BB}
1BB4

It's a simple substitution, only working on the first match since only one slash

Code:
root@OpenWrt:~# a=12341234
root@OpenWrt:~# echo ${a/23/BB}
1BB41234
root@OpenWrt:~# echo ${a//23/BB}
1BB41BB4

Clear as mud now? Smilie
