Not sure I understand. Please write in plain English!

Don't allow any spaces around the = sign when assigning variable. And, use -eq in lieu of == when comparing integer numbers.
Code:
if [ $CantCabe -eq $Cant ] && [ $CantPntCabe -eq $CantPnt ]; then echo "Archivo: OK ";   else echo "Archivo: NOK"; fi
Archivo: OK

One comment.
The bash builtin arithmetics treat a number with leading zero(s) as octal.
Example:
Code:
CantCabe=0023
echo $(( $CantCabe + 1 ))
echo $(( CantCabe + 1 ))

The workaround is
Code:
echo $(( 10#$CantCabe + 1 ))

The [[ ]] compound needs the same workaround
Code:
CantCabe=0023
if [[ 10#$CantCabe -gt 22 ]]; then echo true; fi

In contrast, the [ ] test must NOT get the workaround.
