Is it possible to use egrep to match numbers within a range?

问题

Is there a way to grep/egrep between two sets of numbers?

egrep "SomeText [19999-22000]" /some/file.txt

It's not returning the values. I expect:

SomeText 19999 ffuuu  
SomeText 20001 ffuuu  
SomeText 21000 ffuuu  

回答1:

regex is not the right tool for math stuff (although sometimes it can do), in your case, try the awk:

awk '$2>=19999 && $2<=22000' file

回答2:

You can use the range function , with awk

awk '$2=="19999",$2=="22000"' file
SomeText 19999 ffuuu
SomeText 20001 ffuuu
SomeText 21000 ffuuu
