Works fine for me:
Code:
$ cat file
line1
line2
aaa -bbb -ccc -string1 c,d,e -string2
line4
$ sed -n 's/.*string1 \([^ ]*\) .*/\1/p' file
c,d,e

Post a better sample of your input file and please use code tags.

Code:
sed -n '/\-string1.*\-string2$/p' inputfile | awk '{print $(NF-1)}'

My file content is----
Code:
#interpreter
cd directory
spotlight -verilog file.v -$regression -batch -policy=xyz -rules ABC,abc,pqr -wdir ../other_files
cd ...

In this case i want to extract strings after -rules till the next space.-ABC,abc,pqr

I am using first awk command to find the line--
Code:
awk '/-rules/'{print} > output

because awk print complete line ----

so now output file will have only line which is having -rule, now i have to extract string after -rule till the next space.

As i am new to shell scripting so please explain your answer also.

Thanks

I wonder why you didn't try the sed solution posted by Franklin52 or me! Can you make necessary changes to sed and try again.
Code:
sed -n '/rules/s/.*rules \([^ ]*\) .*/\1/p' inputfile

@michaelrozar17

I am using the same command again and again but its is not working.

Please go through my input files once then reply me for the same.

or if you have any alternative solution for this task.

My input file is ----
Code:
Script---

#interpreter
cd directory
spotlight -verilog file.v -$regression -batch -policy=xyz -rules ABC,abc,pqr -wdir ../other_files
cd ...

First i am using awk command----
Code:
$ awk '/-rules/{print}' script > output

after this i am using the sed command provided by you like---
Code:
$ sed -n '/rules/s/.*rules \([^ ]*\) .*/\1/p' output > out1

now out1 file is empty.
it means sed command is not working properly in this case.

Thanks
Manish

Ok.Can you post the content of the file output as highlighted above. If its same as the highlighted in bule please post few more lines of the inputfile to sed command. And post the sed version you have.Command: sed --version (in GNU Linux)
