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.


Cheers..till next time. hope it helps.

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. 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.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
