![]() ![]() ![]() Number, so to print lines from a file: $ zq file. It's given the name of theĬompressed file and a list of queries. Instead use the paths setting to point to the original file, and specify a pattern that matches the file you want to harvest and all of its rotated files. 0 seconds of 1 minute, 13 secondsVolume 0 00:00 01:13 The Story Behind grep The grep command is famous in Linux and Unix circles for three reasons. It also works with piped output from other commands. The zq program is used to query an index. The Linux grep command is a string and pattern matching utility that displays matching lines from multiple files. $ zindex file.gz -pipe "jq -raw-output -unbuffered '.orderId.id] | join(\" \")'" Matches separated by spaces (which is the default separator). The grep command searches either the input or the file you specify for lines that contain characters that match the specified pattern. Line piped to jq creates a single line of output, with multiple OrderId.ids, then joins them with a space to ensure each individual JSON field orderId.id in any of the items in the document root'sĪctions array (requires jq). $ zindex file.gz -regex 'id:( )' -numeric -uniqueĬreate an index on the second field of a CSV file: $ zindex file.gz -delimiter, -field 2 ![]() The capture group indicates the part that's to be indexed,Īnd the options show each line has a unique, numeric index. This can be done by a regular expression, by field, or by piping eachīy default zindex creates an index of file.gz.zindex when asked toĬreate an index on lines matching a numeric regularĮxpression. Zindex needs to be told what part of each line constitutes the index. query the indexed file with zq from the package.One can follow this workflow to have good performance: Search files in the current directory that is not managed by Git. If the files arent under version control, add -no-index param. The above command will print lines matching all the patterns at once. If you use Windows checkt this out about Linux tools in Windows. Here is the syntax using git grep combining multiple patterns using Boolean expressions: git grep -e 'life' -and -e 'happy' -and -e 'horse'. For someone working with huge text files in Unix/Linux/Mac/Cygwin. ![]()
