Hiding files and documents on Linux
To hide a file or directory in Linux, just to preface its name from a period (.).
For example:
.bash_history
.bash_profile
.ssh
Note that doing this you do not really hide the files because using the option "-a" of the ls command or by selecting "Show hidden files" tab in the Display Explorer and Gnome KDE, one can see these files.
But in this way at least you feel posting :-)
