*USB\ disconnect* ) play /some/othersound. To search for lines of text that contain the given pattern: grep pattern filename this is the line containing pattern. *New\ USB\ device\ found* ) play /some/sound.ogg This command is a little more porewfull than read on already published answerĭifference between follow option tail -f and tail -F, from manpage: -f, -follow[=< <(tail -F /var/log/kern.log) Obviously, I can use egrep -v 'patter1pattern2pattern3. You can do very complicated searches and display the search results in your location list or quickfix list.Coming some late on this question, considering this kind of work as an important part of monitoring job, here is my (not so short) answer. Suppose there is a large text file and I would like to print only the lines that do not match some patterns. However, if you define the greprg properly and use a command such as ( you do want to use the location list, you can use ]q shortcut to navigate it if you have Tim-Popes unimpaired plugin ( )Ĭomplicated searches while within vim: typically if you have to do complicated searches you may have to use the command line. Vimgrep populates a quickfix/location list: using :grep/vimgrep allows you to populate a search list. So, anytime you have to search for an expression, you will have to think/remember whether you should use \) or just ) and other differences. install the GNU grep on your Solaris box (it might already be installed in /usr/sfw/bin, or you might have luck with pkg install //solaris/text/gnu-grep ) or. Solaris' version of grep does not have the -o option. On the other hand, if you use vim’s /pattern option, you are stuck on vim’s default regex engine, which has a different syntax compared to extended regular expression syntax. I am assuming this is a Solaris box you are connecting to. The -i option (for case insensitive matching) will only need to be specified once and will affect all patterns. grep pattern and delete a line from a file. grep recursively only till a certain depth in the directory. which is what the command should have looked like. grep recursively in all directories and sub-directories. If you want to search through multiple files in multiple directories, you can add -R for a recursive search. does not work is because the semantics for the -e option is -e PATTERN, as in. You could filter it into a new file, or process the file line by line and run from that. The grep command searches for the pattern specified by the Pattern parameter and writes each matching line to standard output. The star symbol signifies you want to search in multiple files. In this case run fileA through uniq first to remove duplicates, then use it for the patterns. Also check out the related -L (the complement of -l). Using this you can search the current buffer or multiple buffers/files, using a consistent regex engine. grep -f fileA.txt fileB.txt uniq -c Keep in mind though, if you have duplicates in your fileA, the count won't be correct, since it will grep for them several times. grep -v is your friend: grep -help grep invert -v, -invert-match select non-matching lines. Use a consistent regex engine/syntax: Using :grep/vimgrep allows you to define a grepprg, which can be defined to grep/ack/ag etc.
