Shell Programming and Scripting

I m using the below command for finding a particular file using grep and then copy it.
But the the below command esp the cp is not working

find . -name "CurrentCollector*" -exec grep -l '300173680000D1A8' {} \; | xargs cp {} /ednpdtu7/u01/pipe/current_reprocess -

It's giving the particular error:

cp: ./CurrentCollectorMeterReadBackup_20080709010714909: Function not implemented

--------------------------------------------------------------

It's findin the file CurrentCollectorMeterReadBackup_20080709010714909 but not copying it to the specified dir

plz help me in this

According to the GNU coreutils xargs, you need to specify -I to xargs to tell it to use {} as the substitution glyph.

Code:

find ... | xargs -I {} cp {} target_dir

KSH and Bash don't need the {} quoted, but csh/tcsh does.

i m using this in a script

cd /ednpdtu7/u01/pipe/nav

for i in 300178780001CF60 300179E800021258 300179480001EA7D 300179F800021433 300179980001FD92 300178780001D0CC 300179F800021459 00179C8000206B

do

find . -name "CurrentCollector*" -exec grep -l '$i' {} \; | xargs -I cp /ednpdtu7/u01/pipe/current_reprocess

echo "Completed"
done

I m doinfg this k-shell . is the above command correct in k-shell

No, you need to use double quotes around $i, not single, and the cp appears to be missing the source file now. You want xargs -i cp {} destination

My version of xargs (GNU findutils, indeed) wants the -i in lower case, unless you specifically want to use a different replacement string than {} (which you need to supply as an argument to the -I option, just like in otheus' example).

Why don't you put all those strings in a file, and use grep -f file (or fgrep -f file)? Running find multiple times in a loop seems hugely inefficient.

is the below command correct in k-shell inside a shell script

find . -name "CurrentCollector*" -exec grep -l "$i" {} \; | xargs -I {} cp {} /ednpdtu7/u01/pipe/current_reprocess

and can u tell me how to use grep -f instead of passing so many input to for loop

Good enough. Like era said, you can just use "xargs -i cp {} ..."

You could also use fgrep, but it won't recurse directories (unless it has a -r option).
