Top Forums Shell Programming and Scripting SED - Match a line from a File Post 302425237 by angshuman_ag on Thursday 27th of May 2010 01:37:58 PM

Hi,
Why I need this is so that I can delete the matching line from the file. Or I should be able to replace it with a BLANK.

I saw that if I use option "d" in sed command, it echos all the lines except the given one.

Code:
`sed -n '\/usr\/bin\/7897.xcf/d' file.txt 2>&1`

So, if there is a variable, can I do the same thing with sed ? It will be lot more easier.

One solution could be -

In this example, we tell grep to look for "out dated"--with the space in the middle.
This command searches the file "myfile.new" for the text "out dated"--no matter whether upper-case or lower-case letters have been used--and puts all lines that do not have "out dated" in them into the file "myfile.newer".

Code:
grep -iv "out dated" myfile.new > myfile.newer

NAME
Template::Tools::tpage - Process templates from command line USAGE
tpage [ --define var=value ] file(s) DESCRIPTION
The tpage script is a simple wrapper around the Template Toolkit processor. Files specified by name on the command line are processed in turn by the template processor and the resulting output is sent to STDOUT and can be redirected accordingly. e.g. tpage myfile > myfile.out tpage header myfile footer > myfile.html If no file names are specified on the command line then tpage will read STDIN for input. The "--define" option can be used to set the values of template variables. e.g. tpage --define author="Andy Wardley" skeleton.pm > MyModule.pm See Template for general information about the Perl Template Toolkit and the template language and features.
