## Variables
%%bash name="Uma" echo "Hi $name" echo "Note: it's safer to quote variables like ${name}"
%%bash echo "${name}"
!
is like %%bash
for one-line commands:
!name="Daniel"; echo "Hi ${name}"
!echo "Hi ${name}"
Variables don't persist across cells, for %%bash
or !
. Each cell's commands run in its own subshell.
%%bash readonly UMA="the sweetest" echo "Uma is ${UMA}"
%%bash a=5 b=4 if [ "$a" -eq "$b" ]; then echo "Equal" elif [ "$a" -gt "$b" ]; then echo "Greater" else echo "Less" fi
%%bash for i in {1..5}; do echo $i done
%%bash count=2 while [ $count -lt 5 ]; do echo $count ((count++)) done
%%bash greet() { echo "Hello $1" # $1 is first argument return 0 } greet "Uma the cutie"
%%bash fruits=("apple" "banana" "orange") echo "First fruit: ${fruits[0]}" echo "All fruits: ${fruits[@]}"
