Shell Programming and Scripting

Hi All,
I'm stuck with this issue when I try to display the searched string into a compressed file.

More exactly when I run this script

Code:

for f1 in $(find dir1 -type f -print); do  gunzip -c $f1 | grep -n "gio" | awk -F":" '{print $1-1 "," $1 "p"}'  | xargs -i sed -n {} $f1 ; done

returns

Code:

T Š A1 
T £ A 
΀y£`Ã

but if I run

Code:

gunzip -c <file name> | grep -n "gio"

this work fine

Code:

<file name> = *.Z  *.gz

Any suggestion will be well appreciated.

Thanks in advance for your kind support.

Regards,

Giovanni

Code:

xargs -i sed -n {} $f1

This feeds the compressed file into sed first, and raw, whatever else xargs feeds into it.

If you explained what you were actually trying to do, perhaps we could suggest a way that doesn't need four processes in pipes and one in backticks...

Hi Corona688,
Thank you very much indeed. Yes, I need to display the value not in compress format. I need to have the same possibility to display the current line where the string "gio" is present and the line -1.

For me is not very easy to change my script. Any help will be well appreciated.

Thanks in advance for your kind support.

Regards,

Giovanni

You haven't explained enough -- I can't extrapolate what a broken program does since it's broken!

Display what value? Why are you sedding and awking and grepping? You're trying to rearrange something into something else, but without knowing the input you have and the output you want, I can only make wild guesses.

Show a relevant sample of the (uncompressed) contents of one of the files, and the output you expect from that, so I can help you.
