grep recursive directories
Post 38710 by davidg on Thursday 24th of July 2003 03:24:49 AM

Hi,
Sorry, I will try to make things a bit more clear :
find /tmp -name \*ipt -exec grep pall {} \; -exec ls -l {} \;
The find command you probably know. It searches for files or directorys where you want him to search and to what pattern to match.
So :
"find /tmp" says only start searching in /tmp
"-name \*ipt" says to look for a file or directory ending with "ipt" the \ before the star says to not look for a file or directory named "*ipt" but to make it a pattern
"-exec grep pall {} \;" says that the result of find in /tmp with the pattern ending on "ipt" should do the following : "grep pall /tmp/script" so {} \; is replaced with the current result. It's hard to explain the syntax, I think you should just take this as it is and copy the syntax when you need it
"-exec ls -l {} \;" has the same syntax and executes the ls -l command for the current result. If you don't do this last -exec you don't know what file he grep the text from.
Hope you understand it know. Don't forget there is always a man page from find. I know it is large, but there is so much beautifull to explore in the man from find !!

LEARN ABOUT DEBIAN
dh-exec-install
DH-EXEC-INSTALL(1) dh-exec DH-EXEC-INSTALL(1) NAME
dh-exec-install - Install (and possibly rename) files. SYNOPSIS
#! /usr/bin/dh-exec debian/default.conf => /etc/my-package/start.conf usr/bin/* DESCRIPTION
Being a sub-command of dh-exec(1), this program must not be ran directly, but through dh-exec, which automatically runs all available sub-commands if run bare; or explicitly with dh-exec --with=install. It is meant to be used for dh_install(1) files, and those alone. If it finds that its input is not such a file, it will do nothing, but echo back the contents. The purpose of the program is to extend dh_install(1)'s functionality, by allowing to specify a destination filename. This can be accomplished by a special syntax: the " => " mark between a source and a destination means that the source file should be installed with the specified destination name. For obvious reasons, the source must not be a wildcard, and the destination in this case must be a file, and not a directory. All other non-comment lines are left alone. RESTRICTIONS
Due to the way executable scripts are called from debhelper(1), there is no way to know what options were used for the original dh_install(1). This means, that the --sourcedir option of dh_install(1) will not work correctly when dh-exec-install is in use. IMPLEMENTATION
Internally, the renaming happens by creating a temporary directory under debian/tmp/, and copying (or moving, if the source was under debian/tmp/ to begin with) the file there, with the new name. This is done this way to allow dh_install(1) to do the real copying, and allow its options to continue working, even when renaming is involved. The temporary directory is put under debian/tmp so that it will be cleaned by dh_prep(1) when the clean target gets to run. Thus, no extra code is needed anywhere to clean up the renamed files. ENVIRONMENT
DH_EXEC_SCRIPTDIR Indicates which directory the command-specific scripts should be sought for. If not specified, scripts will be searched for in /usr/share/dh-exec/. FILES
