using linux cmds to match a list names against a bunch of files

I have a slight problem with matching file names.

I have one text file that contains some 160 names. I have a folder with 2000+ files. and some of them contains these 160 names. I am looking for a gr开发者_Python百科ep cmd that can take each name in the text file and try to match it to the contents of the folder.

I am trying to do this in perl, or just straight forward linux cmds, but neither has worked out very well for me because I am not familiar with either of them.

so for example: the text file contains

abc acc eee fff

and the folder will have abcXXX, accXXX, eeeXXX and fffXXX

I need to sort through the list and find out which one were missing.

thx Davy

If you search in the content of the files :

#!/bin/sh  
for i in `cat files`
do
    grep -R $i folder --color
done

and if you search in the filename of the files :

#!/bin/sh 
for i in `cat files`
do
find . -name $i*
done

for file in $(< list); 
do 
   [ ! -f ${file}xxx ] && echo "x: " ${file}xxx
done

list is the file, containing the list of filenames "abc acc ...".
< is redirection - so we read from the file 'list', the same as $(cat list). If the file isn't named 'list', just replace the name.
file is declared in that statement and iteratively bound to all those entries in 'list'. Later it is used as ${file}.
[ ! -f ${file}xxx ] is a test, whether a -f(ile) exists, for abc it searchs for a file abcxxx.
But ! negates the search, so if no such file exists, then echo ... is called. "x: " is just a debug relict.

We can improve that part:

for file in $(< list); 
do 
   [ -f ${file}xxx ] || echo ${file}xxx
done

instead of 'NOT x AND y' we can write 'x OR y' - the meaning is the same, just shorter: the file does exist or echo its name.

|| is short-circuit OR.

If you can arrange for the text file to have each name on a separate line then the following command will do what you need:

ls myfolder | grep -f mytextfile

One way to get each name on a separate line in the text file would be to edit a copy in vi and issue the commands:

:%s/ /^V^M/g
:wq

(^V^M means type "control-v" then "control-m")
