If one assumes he really needs regexp - which is perfectly reasonable in many contexts - the problem is that the specific regexp variety needs to be specified. For example:

egrep '^(100|[1-9]|[1-9][0-9])$'
grep -E '^(100|[1-9]|[1-9][0-9])$'

work fine if the (...|...) alternative syntax is available. In other contexts, they'd be backslashed like \(...\|...\)

This is very simple logic  So no need of regx   Instead go for using ternary operator  var num   89  var isValid    num  lt    100  amp  amp  num  gt  0     true   false    It will do the magic for you
