Question RE find using grep

[fabien]

Hi!

In ly script I would like to be able to copy all the files from a given directory except a few with given extension.

For now I use the command find . -print | cpio -pdvmu, how can I discard files based on extension *.bri* for instance?

Thanks!

Try this:

find . ! -name '*.bri*' -print | cpio -pdvmu

You can do :

find . -print | grep -v '*\.bri*' | cpio -pdvmu

Thanks guys, if I have several file extensions do I put a comma between them?

 

[PHV]

With find only:

find . ! -name '*.bri*' ! -name '*.ext2' ! -name '*.ext3' ... -print | cpio -pdvmu

with grep -E (or egrep):

find . -print |
 grep -E '\.bri|\.ext2|...|\.extN' |
  cpio -pdvmu

Hope This Help

Correction:

find . -print | egrep -v '.*\.bri.*' | cpio -pdvmu

To exclude extensions bri, brj and brk :

find . -print | egrep -v '.*\.(bri|brj|brk).*' | cpio -pdvmu

Jean Pierre, you don't need the leading and trailing '.*'.
Sans offense, j'espère

Ok it works fine but I would like to include also files toto.* as well *.bri.* in one go is it possible?

 

[PHV]

In the find only version, simply insert this:

! -name 'toto.*'

Try this if egrep:

grep -E '\.bri$|\.ext2$|...|\.extN$|^toto\.'

This did not work, with egrep -v (grep -E does not work) I still get the toto.a toto.b etc selected..

 

[aigles]

To exclude files toto.* and *.bri.* :

egrep -v '^toto\.|\.bri\.'
[tt]
-v <= Exclude selected lines
<= Select lines
^toto\. <= starting with toto.
| <= or
\.bri\. <= containing .bri.
[/tt]

cela ne marche pas..

fabien, remove the ^ at front of toto
Et ça va marcher.

Fabien
Please post the complete line that did not work, and tell us what did not work, syntax or results.
Merci

The command does'nt work because filename are prefixed by the directory path : ./ ... /filename

A solution :

tar . -print | egrep -v '/toto\.|\.bri\.' | cpio -pdvmu

There is a problem with this egrep command.
If your directory contains sub-directory with name starting with toto. or containing .bri. all its files will be ignored :
./test/toto.datas/a.a
./in.bri.new/lulu.txt

Another solution :

tar . -print | egrep -v '\(/toto\.|\.bri\.\)[^/]*$'| cpio -pdvmu

Even better:
egrep '\.bri$|\.ext2$|...|\.extN$|/toto\.'

PHV's worked like a charm, thanks guys!

Why do you need to have \. at the end? Does it apply to all expressions in front of it?

 

[PHV]

To avoid exclude files like totosomething.*
