How can I pass multiple variables generated in one function to another funtion? Like for example
fun1(){
var1=$(cat /home/ubuntu/abc1.txt)
var2=$(cat /home/ubuntu/abc2.txt)
var3=$(cat /home/ubuntu/abc3.txt)
}
fun2(){
echo $var1
echo $var2
echo $var3
}
I am new to bash still learning. Couldn't get how to solve this :(
In this case it would be enough to call fun1, variables defined in it will be available in fun2:
#!/usr/bin/env sh
fun1(){
var1="$(cat /home/ubuntu/abc1.txt)"
var2="$(cat /home/ubuntu/abc2.txt)"
var3="$(cat /home/ubuntu/abc3.txt)"
}
fun2(){
echo "$var1"
echo "$var2"
echo "$var3"
}
fun1
fun2
Remember it's a good practice to double quotes variable in most cases to prevent word splitting and to add shebang.
var1=$(< /home/ubuntu/abc1.txt).
