How to cut a line in a text file?

tanboonhoe · #1 (**permalink**) 02-09-04, 12:08

My requirement is to process each line in a text file (raw data). I believe I need to cut each line starting from the first line and follow by the next line until end of file. Each line cut will be appended to a temp file for manupulation before combining them eventually into a text file. Would appreciate for your help. Thanks.

Sounds a bit crazy to me. What's wrong with awk or sed for the job? Can you elaborate on your requirements?

I just want to cut each line in a text file starting from the first line until end of the file so that I can process the content in the record separately. I need to know as well how to move the pointer to the next line until end of file. FYI, I'm new in Shell scripts and awk and sed may be new to me.

With shell you can do :

Code:

while read record
do
    echo $record
done < input_file

With awk :

Code:

awk '{ print tolower($0) }' input_file
