Hiall,I need to deal with a file which seems as follows:
1234
4343
5345345
53453
4343
And what I want to do is to execute follow command to the number of each line:
grep $num1 ./somepath #get num1_res
Then write $num1 and $num1_res to another file which will be:
1234 32
4343 234
5345345 349
53453 78
#...etc
Any good solution by sed?Or some other simple way?
Thanks.
