i have to delete the complete line that match to the strings specified by file
 

Change your working shell to bash and try again.
But one thing, this script will print all lines in all maching files, exect those lines containing $ID. For deletion, you should save output in a seperate file.
Anyway, once share the error message you're getting, if any.

Thank you for you reply!!

My requirement is the file names should be same. I can't change the file names because it is in the server. Those *nantz*.gc files are mandatory files.

I tried changing to bash..Its not working..

Will the below one works?
find . -name "*nantz*.gc" -type f | grep -il "$ID" |xargs sed -i '/$ID/d'

Am not getting any error..It is directing to prompt..Thats all!!

Thanks,

You really should provide examples of the input files, without them you might get answers that might or might not work.

That said; sed -i '/$ID/d' is incorrect, the literal $ID is used (due to the single quotes), not the content of $ID.

Have a look at this: The above also creates backups of the original file (remove the blue part [.org] if all works as desired).

sorry!!!

My intension is:

find . -name "*nantz*.gc" -type f | xargs grep -il "$ID" | xargs sed -i '/$ID/d'

Like I said before: Post examples, and adding to that: describe what it is you want, don't post a (none-working?) one-liner.

From your first post: That's what my command does.

druuna,

Thank you so much for your help!!

I ran with -i option without .org itself. It worked well..Also, I don't find any backup files created for the original files..Please help me in understanding why do you use .org?

find . -type f -name "*nantz*.gc" -exec sed -i '/'$ID'/d' {} \;

In general: creating a backup of the original file is the smart thing to do. If something goes wrong you can always restore it.

Sed's -i option is for in-place changes (the original file is changed). If you want/need a backup you can tell sed to make one using -i.bak.

In the above example a copy, with the extension .bak is made that holds the original file (in my previous post I used .org).

This link might help understanding sed a bit better: GNU sed, a stream editor

druuna,

Just an add to the above post!!

Actually i don't need backup files.Just the original files (*nantz*.gc) is enough. Changes should happen to the original files..That is all what i need..

Thank you again!!

druuna,

i got your reply before i post the above comment. Just added an additional point to my question..

You can remove the backups after you made sure the originals are changed the way you want/need. Better be safe then sorry.....

You shouldn't post your email address (spam etc). Besides that, I don't send information to individuals (all info provided should be searchable by others).
