Server Operation Commands

uptimeThe uptime command is a very simple Linux command that tells us the running time of our system.You can utilize this Linux command to log in to remote servers and see for how long the system is running.Additionally, the uptime command also displays the load average of the remote system and the number of users currently logged in.


# uptime
# uptime -p

The -p flag tells the system uptime in an easily readable format..

wThe w command is another handy but practical server command that displays all the users logged in a system and their activities. Admins can use this command to see users and their processes alongside the load average. It also shows information regarding the remote hosts, login time, idle time, name of the tty, and so on.


# w
# w –short
# w –ip-addr

The –short or -s option displays a shortlist omitting CPU time and login information. Use –ip-addr or -i to print out the IP of the remote hosts.

whoYou can also use the “who” command to display information about remote users. Unlike w, who doesn’t show what the users are doing though. However, who allows a lot of additional options that enable us to get more information effortlessly.


# who
# who -b
# who -d
# who –ips

Simply running the who command gives us the names of the users alongside tty name and time. Use the -b or –boot flag to print when the system was booted, -d or –dead to show the dead processes, and –ips to print out the IP of the remote hosts instead of their username.

usersUsers is one of the most simple server commands for printing only the remote usernames.


# users
# users –version

As with users, whoami only supports the above two options as its argument.

lessUsers is one of the most simple server commands for printing only the remote usernames.The less command is another simple but extremely robust command for Linux sysadmins. It is one of the most versatile Linux commands in the arsenal of seasoned admins due to its sheer amount of features. The main objective of using less is to view files quickly and scroll through them using the page ups and downs.


# less /var/log/custom.log

Since less supports a variety of options and formats, we suggest you see the man and help pages for understanding this command in more detail.

moreThe more command also allows you to scroll through massive files very quickly. You can use this command to view the contents of a file one screenful at a time. Although more offers some useful command-line options, it’s not as powerful as the less command.


# more /var/log/custom.log
# more –help
# man more

You can consult the help page for quickly finding all the available options. Check the manual page if you want detailed information on this command.

tailThe tail command is one of the most useful tools for debugging through log files very fast. This Linux command simply displays the last portions of a file, which are more likely to contain the errors in case of log files. If you’re a sysadmin looking for quick troubleshooting, the tail can be very useful.


# tail /var/log/custom.log
# tail -f /var/log/custom.log

Adding the -f option enables admins to follow their logs as they’re written. Consult the man page for a detailed overview of the tail command.

curlThe curl utility is one of the most powerful Linux server commands for transferring files via the web.
