How do I delete the first column (string) if the line has only one string on the first column?
abc def geh ijk 123 xyz 345 mno
abc def geh 123 xyz 345
A lot of option are available. One of them could be this :
grep " " myfile.txt
The output corresponding of the expected result. This command filter just the line with at least one space.
This works if first string have no space at end, if not this one works too :
awk 'NF > 1' myfile.txt
