$ grep -Rinw ~/bin/ -e 'check_root' -e 'netstat' In addition, it is possible to search for more than one pattern, using the following command. $ grep -Rnw -include=\*.sh ~/bin/ -e 'check_root' This example instructs grep to only look through all. n represent print the lines with line numbers. The strings are extracted from the file and listed in the terminal window. We type strings, a space, jibber and then press Enter. Here, we going to use strings on a binary filean executable filecalled jibber. it will search in that file for that particular string or text and it will print the lines with line numbers. We provide the name of the file we wish strings to search through on the command line. Here we are giving the input to the command like which file you want to search. $ grep -Rinw ~/bin/ -e 'check_root'Īssuming there are several types of files in a directory you wish to search in, you can also specify the type of files to be searched for instance, by their extension using the -include option. grep -n 'devops' hello.txt 1:devops dfsfsg 6:devops dsf dfsf dfds.
The patternlist s value shall consist of one or more patterns separated byThe patterns are specified by the -e option, -f option, or the patternlist operand. If you want to know the exact line where the string of text exist, include the -n option. The grep utility shall search the input files, selecting lines matching one or more patterns the types of patterns are controlled by the options specified. The command you should be using, in this case, is grep. To ignore case distinctions employ the -i option as shown: $ grep -Riw ~/bin/ -e 'check_root' When -R options is used, The Linux grep command will search given string in the specified directory and subdirectories inside that directory. You can also search for a given text in the content of the files as well. You should use the sudo command when searching certain directories or files that require root permissions (unless you are managing your system with the root account). Where the -R option tells grep to read all files under each directory, recursively, following symbolic links only if they are on the command line and option -w instructs it to select only those lines containing matches that form whole words, and -e is used to specify the string (pattern) to be searched. The command below will list all files containing a line with the text “ check_root”, by recursively and aggressively searching the ~/bin directory.
