Shell Programming and Scripting

Hello,

I am trying to remove all the lines in file except lines starting with [

How can i accomplish this?

Thank you very much in advance.

Code:

# grep \\[ file1

# fgrep [ file1

# To update the file if using GNU sed:
# sed -in "/^\[/p" file1

Worked like a charm. Thanks a lot.

I have one requirement. I am reading the value from .csv file. below is the sample
dir_str,test,directory structure
scp_path," /abc/test/a1.sh
/abc/test/a2.sh
/abc/test/a3.sh",path where script files are present
other_files,"/abc/other/o1.txt
/abc/other/o2.txt",path where other files are present

in this csv file i have 3 columns. the value in the second column is provided by the user. I want to extract the details with in the " " after the scp_path word.

how this can be done using sed or awk command?

Can anyone please help?
