I have file of following format:



 1.0
2.0
3.0
4.0
5.0


Is it possible to copy value in first line 1.0 to the beginning of every line in awk? Like this:



 1.0 1.0
1.0 2.0
1.0 3.0
1.0 4.0
1.0 5.0

  • With GNU sed: sed -n '1h;G;s/n/ /p; :j;g;N;s/n/ /p;bj' file In this case, awk is more transparent.

awk 'NR==1 f=$1 print f,$1' file


Output:




1.0 1.0
1.0 2.0
1.0 3.0
1.0 4.0
1.0 5.0


If current line number (NR) is 1 then save column 1 ($1) to variable f. For every line print content of variable f and content of column 1.
