I am running such a program:

 min_val=1
 max_val=100
 int=50 
 if [[ "$int" =~ ^-?[0-9]+$ ]]; then
 if [[ "$int" -ge "$min_val" && -le "$max_val" ]]; then
 echo "$int is within $min_val to $max_val."
 else
 echo "$int is out of range."
 fi
 else
 echo "int is not an integer." >&2
 exit 1
 fi

It report error

 $ bash test_integer3.sh
 test_integer3.sh: line 12: conditional binary operator expectedtest_integer3.sh: 
 line 12: syntax error near `"$max_val"'test_integer3.sh: 
 line 12: ` if [[ "$int" -ge "$min_val" && -le "$max_val" ]]; then'

I have examined carefully line-by-line.

What might be the problem?

Add a shebang and then paste your script there: shellcheck.net

if [[ "$int" -ge "$min_val" && -le "$max_val" ]]; then

You will have to compare against $int in both comparisons:

if [[ "$int" -ge "$min_val" ]] && [[ "$int" -le "$max_val" ]]; then

or,

if (( int >= min_val )) && (( int <= max_val )); then

Your -le doesn't have a left operand.
