Linux copy or move files with xargs




Copying or moving files via terminal or command line are quite easy and basic.

Working remotely in Linux can be done by typing via terminal and executing commands.

Typing the same commands all over again is not quite practical, so a lazy admin comes into play.

Lazy admin doesn't literally mean a lazy admin, but a guy who likes to automate things by using his knowledge and skills like scripting.

Crontab in Linux is a scheduler to automate and run scripts at a specified time.

Crontab is powerful if the script and the settings are configured properly; it will do the task without user intervention.

Some basic commands below to move or copy files and pipe to "xargs" command.

By typing: ls *.log this will filter the output for files with ".log" extension.

     ls *.log | mv $(xargs) /path/another_folder

Move Recursively:


    find  /path/log_folder/ -type f -name '*.log' | mv  $(xargs) /path/another_folder/

If filenames are the same files command will prompt to overwrite.

Command above will move ".log" files to the folder specified. It doesn't need to specify a file name.

To just copy the files for redundancy or backup purposes, use the command below:

    ls *.log | cp $(xargs) /path/another_folder

Copy Recursively:

    find  /path/log_folder/ -type f -name '*.log' | cp  $(xargs) /path/another_folder/

If filenames are the same, overwrite prompt is shown. Files will not be overwritten automatically unless "-rf" arguments is included in the command.

To find files older than 5 days and copy or move those files to another folder use command below:

    find /var/log/xdata/ -type f -mtime +5 | cp $(xargs) /path_to_folder



   find /var/log/xdata/ -type f -mtime +5 | mv $(xargs) /path_to_folder

Before applying any commands to a production environment, test the commands with dummy data and check the output if it is the desired result.

The commands above can be created as a bash script and apply chmod +x Script_name.sh to the file.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

WMIC get computer name

WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
