We can use ls to see the archive file that is created for us. ![]() Through the following examples and explanations, you’ll learn how to use it. So all you really need to know is how to use the command effectively. The tar utility will create an archive file called “page_.” When it comes to finding a particular file or set of files, the find command is your best friend on Linux. tar -cvzf page_: This is the command xargs is going to feed the file list from find to.xargs -o: The -0 arguments xargs to not treat whitespace as the end of a filename.This means that that filenames with spaces in them will be processed correctly. Directories will not be listed because we’re specifically telling it to look for files only, with -type f. The print0 argument tells find to not treat whitespace as the end of a filename. name “*.page” -type f -print0: The find action will start in the current directory, searching by name for files that match the “*.page” search string. The command is made up of different elements. name "*.page" -type f -print0 | xargs -0 tar -cvzf page_ We’ll run this command in a directory that has many help system PAGE files in it. This is a long-winded way to go about it, but we could feed the files found by find into xargs, which then pipes them into tar to create an archive file of those files. We can use find with xargs to some action performed on the files that are found. That’s “almost the same” thing, and not “exactly the same” thing because there can be unexpected differences with shell expansions and file name globbing. This achieves almost the same thing as straightforward piping. For this, you can use the which or locate commands.To address this shortcoming the xargs command can be used to parcel up piped input and to feed it into other commands as though they were command-line parameters to that command. The whereis command does not search for shared libraries or configuration files associated with a command.The whereis command only searches for files in standard system directories, so it may not find files that are installed in non-standard locations.If the whereis command returns unexpected results, you can use the -B, -M, and -S options to specify the directories to search for the binary executable, manual page, and source code files, respectively. In this case, you can use the apt-get or yum command to install the missing package. If the whereis command does not return any results, it may be because the command you are searching for is not installed on your system. Specify the directories to search for the source code file. Specify the directories to search for the manual page file. Specify the directories to search for the binary executable file. Search only for the binary executable file. The following options are available for the whereis command: Option The output shows the locations of the ls and pwd commands, as well as their respective manual pages. ![]() Pwd: /bin/pwd /usr/share/man/man1/pwd.1.gz You can also search for multiple commands at once by specifying them as arguments to the whereis command, like this: whereis ls pwd The output shows that the ls command is located in the /bin directory, and its manual page is located in the /usr/share/man/man1 directory. This would return the following output: ls: /bin/ls /usr/share/man/man1/ls.1.gz ![]() ![]() Where command is the name of the command you want to search for.įor example, to find the location of the ls command, you would run the following command: whereis ls The Linux script command creates a typescript file from your terminal session. The syntax for the whereis command is as follows: whereis command It searches for the specified command in a set of standard directories and returns the paths to the binary executable, source code, and manual page files. Another example: Find and move Here’s another example of a find and copy command I just used, though in this case it was a find and move command. The whereis command is a Linux utility that is used to locate the binary programs, source code, and manual pages for a given command. If you ever need to use the Linux find command to find a large collection of files and copy them to another location, I hope this has been helpful.
