Hi friends,

How to store output of sed command in a variable in shell script???

I tried:

1. ls -l >filenames
2. var=`sed -n '5p' filenames` #5th line of the file
3. echo $var

It is not working.

Please help..........

Thanks in advance.

Code:

$ cat file.txt
this is line 1 of file.txt
this is line 2 of file.txt
this is line 3 of file.txt
$ var=`sed -n '2p' file.txt`
$ echo $var
this is line 2 of file.txt

Seems to work ok to me. Perhaps your ls -l command doesn't produce 5 lines?
