Is it possible to exclude a d开发者_开发百科omain from a grep? What I have tried below doesn\'t seem to work.
I have a line in my.cnf file datadir = /var/lib/mysql The following changes it to mysql3307 as expected.
if [ (`grep -R -l \"${images}\" *` | wc -l) == 1 ] This is not working. If I do this at the command line then it will give me a number.
I am working on a bash script. grep -R -l \"image17\" * image17 will change to some other number when I go through my loop. When I execute the grep above, I get back the following:
Is there some one-line way in bash/GNU tools to block until there\'s a string matched in a file? Ideally, with timeout. I want to avoid multi-line loop.
I know it is possible to invert grep output with the -v flag. Is there a way to only output the non-matching part of the matched line? I ask because I would like to use the return code of 开发者_Stack
I\'m grepping through a large pile of code managed by git, and whenever I do a grep, I see piles and piles of messages of the form:
I have a text file that has a lot of lines and it is laid out like zzzzz | id@host.tld | yyyyy | id@host.tld |
Having trouble with grepping and cutting at the same time I have a file test.t开发者_如何学运维xt.
I have file which contains some data, like this 2011-01-02 100100 1 2011-01-02 100200 0 2011-01-02 100199 3
