Quand on édite un fichier avec nano en ssh, il est possible de coller le contenu du presse-papier du poste client en faisant un clic droit à l'endroit où l'on souhaite voir ce contenu s'afficher.
C'est tout con, mais ça change la vie !
Many Linux servers are administered on the commandline e.g. with an SSH connection. In the following article, I will explain several shell commands that make it easy to view logfiles.
The most important command is tail. Tail can be used to read the last lines from a file. Examples:
Get the last 100 lines from the Debian mail log file:
tail -n 100 /var/log/mail.log
To get all newly added lines from a log file in realtime on the shell, use the command:
tail -f /var/log/mail.log
to quit tail and go back to the command line press the keys [ctrl] + [c]
If you want to get the last 1000 lines from a log file and they do not fit into your shell window, you can use the command "more" to be able to view them line by line.
tail -n 1000 /var/log/mail.log | more
press [space] to go to the next line or [ctrl] + [c] to quit.
If you want to search for a specific term in a large file, the command "grep" comes in handy. Example: We search for the email address "tom@anydomain.tld" in the mail log file:
grep "tom@anydomain.tld" /var/log/mail.log
If you want to view the whole content of a file on the shell, use the command "cat". Example:
cat /proc/cpuinfo
will show you detailed info about the CPU of your computer.
