![]() ![]() Telegraf version installed on the machine is 1.19.2. Create a bash script and call the script instead of entering the command in the config file. Use âgrep -c javaâ instead of âgrep java | wc -lâ. ![]() Give the full paths to the commands, i.e., instead of grep, I tried /bin/grep. I have confirmed this by having the output written to a file on disk using outputs.file plugin. However, it always sends zero (0i) when âgrepâ is included. I think in that way because if I remove âgrep javaâ part of the command, then the command starts to work as it should and send the output to InfluxDB. The update is available in any of the following fix packs. However, this config file does not work as expected because of the grep command, I strongly believe. Fix pack information for: wc and grep performance improvement. Here is another version of grep command to find line count. To do so, I created the following config file:Ĭommands = The GREP is full of global regular expression, representation of global regular expression versions, which is all users. The wc utility displays the number of lines, words, and bytes contained in each input file. Instead, you can use findstr /r "dog cat mouse" if you donât have to apply additional regex features to the search string.I am trying to count the number of listening ports of my java application that is running on RHEL server. we can use the word count wc command with and without the usage of the -u option: grep -l 'Homo sapiens</ name>'.Using wc -l is the preferred solution because it works with -o to count the number of occurrences of the given string or pattern across the entire file. For example, findstr /r (dog|cat|mouse) animals.txt is not supported. A better solution is to use the wc (word count) utility with the -l (lines) parameter, which will count the raw number of lines passed to it over standard input. The pattern that is searched in the file is referred to as the regular expression (grep stands for global search for regular expression and print out). findstr also doesnât know the alternation (match a single regular expression out of several possible regular expressions). The grep filter searches a file for a particular pattern of characters, and displays all lines that contain that pattern. It is interesting to note that the + quantifier (which matches one or more of the preceding character) is missing, as well as the repetition indication in curly braces and the greedy operator (which repeats the search as often as possible). The following command finds all occurrences of â Word position: end of word For instance, /b and /e tell findstr to only display lines with the search term at the beginning or end of the line, respectively. Piping the output through the wc command can be used to count specific kind of. If you are less familiar with regular expressions, you will like that some options can be used as alternatives to regex. redis-cli -r -1 -i 1 INFO grep rsshuman usedmemoryrsshuman:2.71M. cpp head wc The wc program counts lines, words, and characters. And to see the first ten files that are not source code files: ls -l grep -v. Findstr is a much more powerful tool than find as it supports numerous switches and allows you to work with regular expressions (at least with Microsoftâs regex implementation). cpp will show you all your files that are not source code files. ![]()
