# This script gets two arguments:
|
|
# 1) An operand (eq/ne/ge/gt/le/lt)
|
|
# 2) A version number
|
|
# and returns the result of the comparison.
|
|
#
|
|
# Example usage:
|
|
# To test whether the libc version is == 2.26 , run the following command:
|
|
# testLibcVersion eq 2.26
|
|
|
|
# this function takes a string in version format (s.a 2.6.16) and makes it an integer (00020006001600000000)
