Example 2 Filtering JSON array using jQuery grep().Example 1 jquery grep multiple conditions.The -w or -word-regexp option of grep limits the output to exact matches only. Use the below-given command if you only need the exact occurrences of a word. The output highlights the string you wanted to grep. The Linux grep command illustrated in the earlier example also lists lines with partial matches. Since grep does not support the pipe symbol as the alternation operator, you need to use the escape character (backslash \) to tell the grep command to treat the pipe differently.įor example, to search for the words extraand valuein the sample.txt file use this command: grep 'extra\|value' sample.txt Do not forget to use the backslash before the pipe character.

The deprecated version of extended grep is egrep. grep -E 'pattern1|pattern2' fileName_or_filePath This option treats the pattern you used as an extended regular expression. The latest way to use grep is with the -Eoption. grep 'pattern1\|pattern2' fileName_or_filePath Use the backslash before pipe | for regular expressions. The patterns need to be enclosed using single quotes and separated by the pipe symbol. The basic grep syntax when searching multiple patterns in a file includes using the grep command followed by strings and the name of the file or its path.
