Let's see a few examples of how to compare Strings in a Bash Script,
Example 1: using [ ]
#!/bin/bash
name1="Mike"
name2="Mikey"
if [ "$name1" = "$name2" ]; then
echo "Both names are the same."
else
echo "Both names are not the same."
fi
Example 2: using (( ))
#!/bin/bash
name1="Mike"
name2="Mikey"
if (( "$name1" == "$name2" )); then
echo "Both names are the same."
else
echo "Both names are not the same."
fi
Example 2: using [[ ]]
#!/bin/bash
name1="Mike"
name2="Mikey"
if [[ "$name1" == "$name2" ]]; then
echo "Both names are the same."
else
echo "Both names are not the same."
fi
