linux上的grep命令（尤其是grep --exclude）

Question

I'm newbie on linux issues and before asking here I googled it however I couldnt find a clue about grep --exclude.So I wonder what does the line below ?? Thanks in advance

grep --exclude=\*.svn\* -r REVISION 1.0.0.8/*1.0.0.8.config > 1.0.0.8-REVISION.txt

SOLVED BY MYSELF

search REVISION on "1.0.0.8/*1.0.0.8.config" file exluding .svn file and send output to 1.0.0.8-Revision.txt

Answer 1

To grep through a directory while excluding various file types (in your example anything prefixed with .svn ) you probably want to do the following:

grep -r "SOMETHING" --exclude="*.svn*" /path/to/directory >  1.0.0.8-REVISION.txt 2>&1

This will grep through all files within a directory recursively, then post the matches to a file called 1.0.0.8-REVISION.txt which is located relative to where you are currently searching.

If you provide more information abut exactly what you're trying to grep/find I can update my answer with something that will work exactly for your case.

Answer 2

you can find grep on man pages here .

what exclude does:

--exclude=PATTERN:

• Recurse in directories skip file matching PATTERN.

your command will search, recursively, in all directories, skipping file pattern "*.svn*" and searching for file pattern "1.0.0.8/*1.0.0.8.config > 1.0.0.8-REVISION.txt"
