Bash supports three types of loops: for, while, and until.
The ‘for’ loop iterates over a list of items. For example:
for i in {1..5}; do echo $i; done
This prints numbers 1 to 5.
The ‘while’ loop executes as long as the condition is true. Example:
i=1; while [ $i -le 5 ]; do echo $i; let "i++"; done
This also prints numbers 1 to 5.
The ‘until’ loop runs until the condition becomes true. Here’s an example:
i=1; until [ $i -gt 5 ]; do echo $i; let "i++"; done
Again, this prints numbers 1 to 5.
