Hello, everyone. I am trying to create a script, and one part requires showing lines with numeric values. My basic syntax is: echo $i | grep [0-9] For example, I set i=12345, it should output 12345.

Hi, Does anybody know how to code a regular expression (for use with some grep like tool) which will search for the word 'vat' but exclude the word 'pri**vat**e'. I've taken over a project which has hundreds of references to VAT (some hard-coded, some not) and as the VAT rate in the UK is changing on January 1 I need to update the proj...

I've got this little script in sh (Mac OSX 10.6) to look through an array of files. Google has stopped being helpful at this point: files="*.jpg" for f in $files do echo $f | grep -oEi '[0-9]+_([a-z]+)_[0-9a-z]*' name=$? echo $name done So far (obviously, to you shell gurus) $name merely holds 0, 1 or 2...
Is there any way I could use grep to ignore some files when searching something, something equivalent to svnignore or gitignore? I usually use something like this when searching source code. grep -r something * | grep -v ignore_file1 | grep -v ignore_file2 Even if I could set up an alias to grep to ignore these files would be good. ...

Ok so heres the coding i hav...
My shell has a call to 'fortune' in my .login file, to provide me with a little message of the day. However, some of the fortunes begin with one leading whitespace line, some begin with two, and some don't have any leading whitespace lines at all. This bugs me. I sat down to wrapper fortune with my own shell script, which would remove a...

I am trying to understand why grep built by me is much slower than the one that comes with the system and trying to find what compiler options are used by grep that comes with the system.

I was using the return value of fgrep -s 'text' /folder/*.txt to find if 'text' is in any .txt file in /folder/. It works, but I find it too slow for what I need, like if it searches for 'text' in all the files before giving me an answer. I need something that quickly gives me a yes/no answer when it finds at least one file with the 't...

I'd like to use grep to find out if/where an html class is used across a bunch of files. The regex pattern should find not only <p class="foo"> but also <p class="foo bar foo-bar">.
