Hello,
I am trying to write a simple bash script that will grep all files
in a directory (except ones that start with "00") for certain bad
keywords. Here is what I have so far:
#!/bin/bash
# This is a simple script to check all sql scripts for bad keywords
BAD_KEYWORDS='spool echo timing commit rollback'
for i in $BAD_KEYWORDS; do echo "*********************************"; echo "GREPing for bad keyword '$i'" echo "*********************************"; grep $i ./*; done
However, I'm not sure how to make it not grep the files that start
with "00". Can anyone help me with this?
Use xargs, since it will buy you the extra feature of being able to search through arbitrarily large numbers of files:
for _word in ${BAD_KEYWORDS} ;do find . | grep -v '^/00' |\ xargs grep "${_word}" /dev/null done
Tips:
- The quotes in "${_word}" are probably optional, but it's better to be safe than sorry :-)
- The /dev/null is there so that grep will get at least 2 file arguments, even if there is just one file in the current directory, effectively forcing grep(1) to print the filename of this one file if it happens to match the pattern.
Cool, I think I get it for the most part. However, what exactly am I doing when I am piping to xargs? I can see that the filenames not starting with '00' will be piped, but what does the '\' do? Sorry, I am really new to scripting and *nix in general. But I am a programmer so I learn fast.
Thanks!

The '\' means pretend I typed the next line on this line he used it because most mailers wrap the e-mail lines at 80 characters, but it needs to be on one line to work. If you wrote it on one line in the script file, you can omit that '\'
