![]() ![]() For example, 0-9 is a shell expression meaning any file with a single character name that isnt a digit. Second, always quote your expressions - the shell uses wildcards and your expression could be expanded by the shell if it fits something. Hence when the egrep's result was sent to grep -v command, it failed to match the pattern. grep uses regular expressions, not wildcards - thats the first thing you should know. ![]() uc_needle=$(printf %s "$needle" | tr '' '' echo. The 'ERROR' pattern did not match grep output statement as the 'ERROR' between the STATUS tags in grep output had some special characters added to it by the -w flag. The second form just execs commands and tests their exit status.įor a case-sensitive string search of the value of the variable needle in the value of the variable haystack: case "$haystack" inįor a case-insensitive string search, convert both to the same case. Note that the first example uses which allows direct comparisons and various useful operators. The -F option says to treat the argument as a string rather than a regular expression. The -q option says to not emit output and exit after the first match. The -i option of grep says to ignore case. Grep exits with success if and only if it finds a match. ![]() Please let me know if you need more informa. The if statement tests the exit status of the rightmost command in a pipeline - in this case grep. '-ignore-case' does not work for CocList grep Issue 92 neoclide/coc-lists GitHub Hi there, I have tried :CocList -I -ignore-case grep and inside coc-settings.json add '-ignore-list' to array, both gives the exact same case sensitive result. The key here is that you are piping a command output to grep. If you want to ignore case, and neither string contains a line break, then you could use grep: #!/bin/bash eblock at 9:08 The desired behaviour is achieved simply by dropping -i - I don't understand what the question is. Try replacing echo hello with a command of your choosing. 369 1 11 How about an argument for the script Inside the script you check 1 for any string you like and create a case statement with or without case-sensitive search. Try changing the string hello on the right, and it should no longer echo it works. You can combine the recursive option with the ignore case option (-i) to find a specific text like hostname by ignoring the case in your config files and. First here's a simple example script that doesn't ignore case: #!/bin/bash ![]()
