I tried lot of ways to match a string but my if statement don't work. I want to test if the first parameter is equal to his reverse.
For example if [ $1 = "something" ] may work but i don't know how to do it if i'm using my reverse variable
#!/bin/bash
echo "la string en parametre" ${1}
reverse= echo -n $1 | rev
if [[ $1=reverse ]]; then
echo "est pas un palindrome"
else
echo "est un palindrome"
fi
First, this doesn't work:
reverse= echo -n $1 | rev
Use command substitution:
reverse=$( echo -n "$1" | rev )
Second, this won't work:
if [[ $1=reverse ]]; then
There must be spaces around = and to access a variable, you need a dollar sign:
if [[ $1 = $reverse ]]; then
In sum, try:
echo "la string en parametre: '$1'"
reverse=$( echo -n "$1" | rev )
if [[ $1 = $reverse ]]; then
echo "est un palindrome"
else
echo "est pas un palindrome"
fi
