[programmer321]

Hello,

I need to search from a text file all those number from the lines which which lie in the range 1 to 120. Say I have a file with number:
1
2
3
900
1200
so on...

I want to only those lines which has numbers in the range from 1 to 120.

Regards.

awk '$1>=1 && $1<=120' file

Thanks Salem for the response. Can u suggest me a solution for finding a list of missing number from a given range say between 1 and 120. 

Regards.

Output all the numbers from the above search into one file
Generate another file containing all the numbers you expect
Use 'diff' to work out what's missing

awk 'END {
for (i=min; i<=max; i++)
  if (!(i in x)) print i } 
{ x[$1] }
' min=1 max=120 file
