# Basic syntax:
# This will run command_2 after command_1 regardless of whether command_1
# completes successfully or not:
command_1; command_2
# This will run command_2 after command_1 if command_1 completes successfully:
command_1 && command_2
# This will run command_2 after command_1 if command_1 fails:
command_1 || command_2
# This will pass (pipe) the standard output of command_1 to command_2:
command_1 | command_2Source : https://dev.to/0xbf/run-multiple-commands-in-one-line-with-and-linux-tips-5hgm | Last Update : Mon, 08 Aug 22

# Basic syntax:
for i in a b; do echo $i; printf "$i\t$i\n"; done
# Where:
# - each command in the for loop needs to be separated by semicolons. Here
# we echo $i and then print $i<tab>$i<newline>
# - over several lines this would be equivalent to:
for i in a b
do echo $i printf "$i\t$i\n"
