  • How to "grep" out specific line ranges of a file

    - by Mike
    There are often times I'll grep -l whatev file to find what I'm looking for. Say the output is 1234: whatev 1 5555: whatev 2 6643: whatev 3 If I want to then just extract the lines between 1234 and 5555, is there a tool to do that? For static files I have a script that does wc -l of the file and then does the math to split it out with tail & head but that doesn't work out so well with log files that are constantly being written to.

    - by user346134
    Hi all, I am doing some improvements to an application in vs2008 in c++. When i try to edit resources (for example add an entry in the string table), the vs2008 editor changes the rc file language from LANG_ENGLISH to LANG_NEUTRAL and a non english text is replaced with question marks.
