Linux folder with special characters

Operating system or even applications programs does restrict some characters since it's either used by the system or it is not permitted for some other reasons.

In Linux special characters like ampersand, dashes and other special characters should not be used as folder names or even file names.

But some users or even IT folks violate this rule without knowing the consequences it holds.

Of course, whatever characters available on the keyboard should be used or else what's the point of having them on the keyboard. :)

But there are consequences in using those mentioned characters.

Empty log or replace large files

Log files can easily occupy the space of a drive.

To empty a log file or a text file:

In Windows open command prompt and type:

echo "First Line" > Packets_2018.log

The log file will be replace with the word "First Line" and only a few bytes in size. Whatever was the content before on that log file is ditch away. So, be careful in emptying a file it's not reversible,

In Linux open Terminal and type:

echo "Line 1" > Packet_logstash.log

Till next time..Cheers!
