Comando Explicación

say Convert text to audible speech

echo write arguments to the standard output

ls list directory contents

ls -l List in long format.

ls -F Display a slash (`/') immediately after each pathname that is a

directory, an asterisk (`*') after each that is executable, an at

sign (`@') after each symbolic link

ls -a Include directory entries whose names begin

with a dot (.)

cd shell built-in commands

cd .. / para acceder a un subdirectorio de nuestro mismo nivel.

cd x se va al nombre de la carpeta

cp copy files

cp -r

If source_file designates a directory, cp copies the directory and the entire subtree connected at that point. If the source_file ends in a /, the contents of the directory are copied rather than the directory itself. This option also causes symbolic links to be copied, rather than indirected through, and for cp to create spe- cial files rather than copying them as normal files. Created directories have the same mode as the corresponding source direc- tory, unmodified by the process' umask.

mv move files

rm remove directory entries

rmdir removes the directory entry specified by each directory argument,

provided it is empty.

mkdir creates the directories named as operands, in the order specified

chmod (modo simbólico) change file modes or Access Control Lists

pwd return working directory name

cal (con sus variantes)

displays a calendar and the date of easter

cal [-jy] [[month] year]

cal [-j] -m month [year] ncal [- jJpwy] [-s country_code] [[month] year]

ncal [-Jeo] [year]
