Hi,

I would like to know How to use use sed for manipulating string for the following situation.
Basically my objective is to check validity of the filename in my shell script.
I am getting a parameter like this for my shell script.
Check my folder is having some space.

$1=/root/krishna mohan/file.txt

I am trying to use sed so that I can mutate the above file path like below and further use ls command.
/root/'krishna mohan'/file.txt

ls /root/'krishna mohan'/file.txt

Ofcourse I do know that I can use single quote in the begining and end.But I will have problems if I am getting above parameter with some mask/pattern like
/root/krishna mohan/file*.txt
Here keeping single quotes in the begining and end won't work.

Kindly suggest me the solution How to keep quotes for any text between / and / which has space.

when you use the variable $1, use double quotes.

yeah But it is not working in following case..can u pls suggest on this
Here is the input parameter it comes for me.

$ ./sample.ksh '/root/krishna mohan/file*.txt'

sample.ksh
********

input="$1"

ls -m $input
ls -m "$input"

**********

above command are not able to interpret and list the exact files..

Thanks
Krishna
