Merging lines using AWK
Hi,
Anybody help on this.
I want to merge the line with previous line, if the line starts with 7.
Otherwise No change in the line.
Example file aa.txt is like below
122122
222222
333333
734834
702923
389898
790909
712345
999999
My output should be written in another file called bb.txt
122122
222222
333333734834702923
389898790909712345
999999
Your help is very much appriciated.
