How to find/replace a character within a string?

[goyalpdm]

Hi,

Am using Ksh and have the string in a variable. The string contains ' and would like to append / before same. So ' should be replaced as /'. Please advise.

Thanks,
Sachin

Hi

As far as I know,this should work in [tt]ksh[/tt] too :

your_string=${your_string//\'//\'}

Ps : I think this question belongs to forum822 ( UNIX Scripting ).

The code returns bad substitution.

PS: Not too sure on how to change the forum. If you can, please do it for me.

Try:

str=$(echo ${str}|sed "s:':/':g")

Perfect! Thanks a ton!

Can please suggest the command if ' should be modified to \' (instead of /' as mentioned earlier)?

I tried str=$(echo ${str}|sed "s:':\':g"): but it is of no help.

You need to quadruple the '\' character:

str=$(echo ${str}|sed "s:':\\\\':g"

Double, because between double quotes you need to quote the special char '\' ...
Double again, because sed needs you to quote the special char '\' in order to get a '\' without special meaning ...

Perfect again! Good learning. Thanks a ton.
