Testing/Comparing Numbers

The primitives available for comparison of numeric values are

• -eq, -ne: equal, not equal.
• -gt, -lt: greater, less than.
• -ge, -le: greater or equal, less or equal.

For example:

    #!/bin/sh

    if test $# -le 5
    then
        echo Less than or equal to five parameters.
    else
        echo More than 5 parameters.
    fi
    exit 0
