Terminal text color question

[dalexunil]

When I run ~$ ls from Terminal there is a file/dir that is displayed in red. When I try to cd into it I can't seem to find a legend explaining for me what this is indicating. Can't be too good I suspect since it is in red! Thank you. D

Red means an archive file. See also here.

You can also do

Code: Select all

ls -F

directories are marked with a "/", executables with a "*".

Also

Code: Select all

file some-filename

will tell you what the file is:

Code: Select all

file *
a1:                 ASCII text
bin:                directory
dat:                directory
systemctl.help.txt: ASCII text
