In other locales, the standard input may be If the standard input is searched, a pathname of (standard input) willīe written, in the POSIX locale. Pathnames are written once per file searched. (The letter ell.) Write only the names of files containing selected This means any investment you made in learning Linux commands like grep will be useful for many years to come.Īnyway, let's understand what does -l option on grep command does here is what the grep -l command option does (from UNIX standard): Linux has already survived for more than 40 years, and I am sure it will remain relevant in the coming years as well. Hence, I also suggest you join one of these online Linux command line courses to learn Linux fundamentals in depth. This option of grep only shows filenames that contain matching text.ītw, a good knowledge of essential Linux commands like find, grep, awk, and sed goes a long way in improving your Linux skills as well as improving your productivity. Since many files contain database references, you might get a lot of data on output, so if you are only interested in all the files containing matching text, you can use the grep -l option. For example, when you are searching for some configurations like a Linux or database hostname across all configuration files in your application host, then you just want to see which file has contained those references. Still, sometimes you only want to grep to show just filename and path and not the matching text. This is actually required and needed in most situations. The grep command from Linux is one of the powerful commands to find files containing some text, but when you use grep, it not only print the file name but also the line, which is including the matching text. This results in this very different output: That's nice, but what if I want to see the last modification time of these files, or their filesize? No problem, I just add the ls -ld command to my find command, like this: In my current directory, the output of this command looks like this: ![]() To get started, this find command will find all the *.pl files (Perl files) beneath the current directory: type f -name "*.java" -exec grep -l StringBuffer \ įrom time to time I run the find command with the ls command so I can get detailed information about files the find command locates. type f -not -name "*.html" # find all files not ending in ".html"įind files by text in the file (find grep)įind. type f \( -name "*cache" -o -name "*xml" -o -name "*html" \) # three patternsįind files that don't match a pattern (-not)įind. ![]() iname foo -type f # same thing, but only filesįind. iname foo -type d # same thing, but only dirsįind. iname foo # find foo, Foo, FOo, FOO, etc.įind. name foo.txt # search under the current dirįind /users/al -name Cookbook -type d # search '/users/al' dirįind /opt /usr /var -name foo.scala -type f # search multiple dirsįind. Almost every command is followed by a short description to explain the command others are described more fully at the URLs shown:įind / -name foo.txt -type f -print # full commandįind / -name foo.txt -type f # -print isn't necessaryįind / -name foo.txt # don't have to specify "type=file"įind. ![]() ![]() If you just want to see some examples and skip the reading, here are a little more than thirty Linux find command examples to get you started. In this article I’ll take a look at the most common uses of the find command. It can search the entire filesystem to find files and directories according to the search criteria you specify. Besides using the find command to locate files, you can also use it to execute other Linux commands ( grep, mv, rm, etc.) on the files and directories that are found, which makes find even more powerful. Linux/Unix FAQ: Can you share some Linux find command examples?
