Find file based on list

[Michael Allmer]

I have a file that contains a partial file name.
Example name.txt contains
573_-_mm-cubeside180
573_-_mm-cubeside270
573_-_mm-cubeside90
573_-_mm-datum-ring
573_-_mm-datumringstand

I want to use 'find' to located them on disk with adding file extention.
example: find /tool -name 573_-_mm-cubeside180*.prt
And use the output from 'find' to exec ls -l on the full path of the file.

Hi Mike:

Give your file named 'name.txt' with each line representing a filename, you could do:

while read NAME
do
find /tool -xdev -type f -name "${NAME}*.prt" -exec ls -l {} +
done < name.txt

I use the -xdev' so as not to cross mountpoints. I use the '-type f' to restrict us to files and not directories, etc. The use of the "+' terminator means that multiple arguments (here, filenames) can be collected and passed to one instantation of the command ('ls'). This is quite efficient.

Regards!

HI,
You can used find command with for loop
i.e.
for i in `cat name.txt`
do
find . -name $i -exec ls -l {} \; >/tmp/find.out
done

If you have lots of files or a very large filesystem to search, you don't want to use a stinkin' for loop with find(1).

Possibly something like:
find /tool $(
awk '
BEGIN { print "(" }
{
print "-name " $1 "*.prt -o "
}
END { print " -name bad_Xname )" } ' < name.txt
) -exec ll +

Hi (again):

@ Dennis: That's a very nice solution to keep from abusing the server! :-)

@ Mike: No points for this comment, please.

Thanks for all the assistance.

I just realized there is a simpler solution than my awk script above. The key thing is to use vector methods and not loops.
find /tool -name "*.prt" | fgrep -f name.txt | xargs ll
