Manage Files

ls -> List files ls l ls -a ls -lrt ls -d ls -R

ls --color=no
ls --color=yes
ls --color=auto

By default ls sorts the files alphabetically atime - The last time when the file was accessed mtime - Last modification time ctime - Last metadata modification time (Permissions change, location of the file, etc)

-t -> Order by mtime -tc -> Order based in mtime -tu -> Order based in atime Always from new to old

-s -> Displays the actual allocated disk space next to each directory -S -> Order from largest to smaller ls -m -> Prints the files separated by commas ls -Q -> Prints the filenames in Quotes ls -l —time-style=local/iso/full-iso -> Changes the way how the date is formated in long format

ls -A -> No muestra .. . mkdir -> Create directory cp -> Copy files mv -> Move files

To find files: which -> looks for binaries in $PATH (Executable files) locate -> uses a database, built by updatedb find -> The best tool

sudo find / -name "hosts"
sudo find / -name "*hosts"
sudo find / -type f -size +100M

sudo sh -c "find /etc/ -name '*' -type f | xargs grep 127.0.0.1"

-type f -> For files -type d -> For directories

mkdir -p find/contents

sudo find /etc -exec grep -l student {} \; -exec cp {} find/contents/ \ 2>/dev/null

-exec tells find: “For every file you find, execute this specific command on it.”

The -l flag tells grep not to print the matching lines, but instead to return a success code only if it finds the word.

In find, multiple -exec parameters act at as a logical AND. The second -exec will only run if the first -exec was successful.
