Re: [newbie] grep search
Hi,
You may use the find command. find allows you to go through a directory
tree and perform some tests and actions on it. For example, in your case
you want something like
find / -path /mnt -prune -o -type f -exec grep my exp {} \;
Here, the / means start in /, the '-path /mnt -prune' means if the path
is of the form /mnt, don't go into it, the '-o' is a logical or, '-type f'
means only regular files, and the -exec says what command to execute
(the '{}' is replaced by the file name). find has many other option, all
of which you can read about in man find. Note in particular the -mount
option, which might be a simpler way to do what you want

Go to http://www.mandrakestore.com Well you don't want to search /proc either The easy way is probably to use a list that you develop with ls and sed ls -I 'mnt' -I 'proc' -R -1 -d / | grep '/?|(yoursearchstring)' should generate the list of files matching your search with each match headed by its enclosing directories. That is is you are looking for a match in the file name. Now if you are looking for a match in the file contents, it is a little trickier,,, grep -i -l --exclude 'mnt|proc' -e (yourpatternwithoutquotes) / The -i is for ignore case and the -l lists only the file, not the matching lines within it. The --exclude implies recursive (-r or -d recurse). Civileme Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Re: [newbie] grep -r *.c doesn't find files
On Sunday 12 August 2001 06:44 am, George Petri wrote: Surely, grep can do something this basic, can't it (didn't the author of grep write c programs too:)? I don't like find and its complexity very much. Recall that the tools in Unix are (or at least were at one point) designed to do one thing well, and do it simply. If there is a command that will return a list of files, there really isn't a need for that functionality to be put into another command that does something else. Unfortunately, find can be difficult to learn to use and it does have a lot of options. I tend to prefer something like : # grep whatever `find . -name *.c` By using the backquotes, that simply substitutes the filenames that find returns right into the grep command line. But that can be impractical as find could return a great deal of filenames (thus a very long command line). But it's easier to type :). It does turn out that the xargs solution is likely less stressful on the system. Grep actually can recurse - by using the -r switch on grep, it'll go through all files in a directory and directories within the parent directory (or matching filenames). 55 days? That's 2 months! My X seems to die under heavy loads -- under that load average of 51.29 on a single Pentium II, X didn' yeah, but I usually don't run the load average quite that high :). I don't think it's necessarily a case of the X server dying, but maybe the system is so stressed out that it's hard for it to respond to keystrokes or anything else. Recently I've noted a few tiimes where this has happened to me - sometimes by killing the X server and getting out of KDE I can reclaim the system. So far, I haven't had to reboot -- not in the last two months or so :). George -- David E. Fox Thanks for letting me [EMAIL PROTECTED]change magnetic patterns [EMAIL PROTECTED] on your hard disk. ---
Re: [newbie] GREP
The grep command is a search tool for the command line. You can use it to fild specific strings in selected files etc. To learn about grep use the man command as in "man grep" (without the quotes). The man pages are a little criptic, but with a little practice and carefull reading, you can find a lot of information there. Ernie On Fri, 22 Oct 1999,Shannon M.

Re: [newbie] GREP
I usually use grep to search either files or command output for string ocurrences. Ex. grep "bryanm" user.txt result would return the contents of any line that contained bryanm in a file called user.txt and dump the results to a file called result leave result off to dump to screen You can do many things with it. The man page, IMOHO, is all lecture with little practical application. The best source I have found on most *nix commands is Unix Unleashed.

For example, type the following at a command prompt: rpm -qa | grep sendmail that will show you all the packages you have installed which have "sendmail" as part of their name. Or you can try "cat somefilename | grep something" and that will search a specific file (typically a log file) for all occurrances of whatever you're requesting and print 'em all out for you on the screen. It's a very handy utility. :-) John

Re: [newbie] grep and replace
Maybe this would do it (as a shell script): #! /bin/sh for $i in `find .`; do cp $i $i.old cat $i.old | sed -e "s/MarketingWorks\/Collard Associates/MarketingWorks" $i next; I am NOT a shell script guru- you can tell because my for loop syntax is wrong, and I'm not sure what the proper way to write it is. I hope I get my idea across, though. You might run it as `script 2 /dev/null` because it will generate an error message for every directory under ./ as I couldn't figure out a way to get `find` to list only files, or `ls -R` to not print out directory names. With this pseudo-script, you also get backups of your HTML files (with a .old extension) in case it screws up. If it works, then you can rm `find . |grep .old` to recusively remove all old files. I think. -Matt Stegman [EMAIL PROTECTED] On Thu, 2 Sep 1999, James Stewart wrote: Been investigating the problem I posted yesterday a bit more, and have a slightly better way of expressing it now ;) What I want to do is like issuing: grep -r MarketingWorks\/Collard Associates /home/httpd/marketingworks.co.uk but instead of listing the results I want to replace it with simply MarketingWorks Another way of looking at it is issuing perl's s/MarketingWorks\/Collard Associates/MarketingWorks/; but recursively through the directory structure.
