![]() This is very useful to search strings, but It will take little longer time. We can search strings including sub folders using the following approach We can search strings recursively using the following Solaris 10 includes grep utility it won’t work recursively like in many Linux flavours. In post we are going to learn about how to search string in all files in Solaris. Grep -exclude=*.o -rnw 'directory' -e "pattern"Ībove will exclude searching all the files ending with. This will only search through the files which have. Grep -include= -rnw 'directory' -e "pattern" Along with these, –exclude or –include parameter could be used for efficient searching. grep string filename(s) - looks for the string in the files. r is recursive, -n is line number and -w stands match the whole word. Note that some of these commands are different on non-Solaris machines - see SunOS differences. The list of techniques are describe below In this example we will search directories /etc /usr/share and/home` in single command by adding them to the end of the command.In this post we are going learn about how to find search string in files and folders in Linux and Solaris machines. In some cases we may need to search multiple directories those resides in different path. In previous examples we have provide only single directory to search. ls -dR actually does what the documentation says: '-d Directories are listed as plain files (not searched recursively).' ls -R on the other hand does list subdirectories recursively. $ grep -r -i "test" /home/ Search Case-Insensitive Search Multiple Directories The real question should include a description of 'work', so that we can answer why ls -dR 'does not work'. In this example we will search test case-insensitive which means alternative like TEST Test etc. If we want to look incase-sensitive we should provide -i option. $ grep -r -exclude "*.pyc" "python3" /home/ Search Case-Insensitiveīy default grep will search case sensitive. For example if we only want to search python scripts but not pyc or python cache files we can specify to exclude pyc. We can also specify the file name patterns or extensions we want to exclude. $ grep -r -include "*.py" "python3" /home/ Specify File Name Pattern or Extension Exclude Specified File Name Pattern or Extension In this example we will search for import term. For example if we want to search the Python script or code files content we can use *.py file pattern to look only those files recursively. We can specify file pattern to search recursively. In other implementations, basic regular expressions are ordinarily less powerful. ![]() In GNU grep, basic and extended regular expressions are merely different notations for the same pattern-matching functionality. $ grep -r "import" /home/ Recursive -r Option Specify File Name Pattern or Extension grep understands three different versions of regular expression syntax: basic (BRE), extended (ERE) and perl (PCRE). In this example we will search files those have string import. We will start with a simple example and only specifying recursive option -r which is shortcut for “recursive”. Introduction to Linux Grep Command With Examples Recursive -r Option Recursive behavior makes it more powerful by looking sub directories and files. recursive search <1>: File and Directory Selection.![]() We can search file content according to extension. Portability note: Solaris 10 grep lacks -q portable shell scripts. What makes grep powerful is that it can search file contents. Grep is very useful command to search files and directories.
