Show lines between frist and last appearance
Dear all,

I want to show all lines between the first and the last appearance of a string in a file. This string is a input parameter of a script. I have some ideas with grep -n but i'm sure that I can get a better solution with SED or AWK

thanks!

As a start, both in awk and sed you can use ranges, written like
Code:
.. /start/,/end/ ..

Sorry but, if you could write the complete command I would understand better... I know how to declare "start" pattern but no "end" pattern, and i supose i must write code to print lines ... thank you!

start with the line that begins with the character 3 /^3/
end with the line that starts with the chacter 8 /^8/
^ means the start of the line

Need ls to show number of lines in each file

Hi, I need a command that would let ls show number of lines in each file rather than file size in KBs. I tried using wc -l as a source of input to ls but I found a problem cutting the file name since wc generates a space delimited list. Any suggestions? Thanks. GmMike. (1 Reply)
