merge two files line by line...

I have 2 files:

file1:

x y z
a b c
--
x y z
d c f
--
x y z
t h y


file 2:

12:00
12:01
12:02


I want to merge these files such that the output looks like:

x y z
a b c
12:00
x y z
d c f
12:01
x y z
t h y
12:02

Is this easily possible?

Thanks in advance

One possibility...

awk 'NR==FNR{a[NR]=$0;next}/^--/{$0=a[++nr]}1' file2 file1

If there's no '--' in the last line of file1 you may have to change it to...

awk 'NR==FNR{a[NR]=$0;next}/^--/{$0=a[++nr]}1
END{print a[++nr]}' file2 file1

(Or add a final '--' to file1 instead, to keep the awk program terse.)

here "--" too?

[GNU sed]

$ sed '/--/R file2
/--/d' file1

[...]

awk '$0 == "--" {getline < "file2"}
{print}
END {while ((getline < "file2") > 0) print}' file1

Yeah... can be exotic this solution :

$ awk '/--/{print NR "s/" $0}' file1
3s/--
6s/--
9s/--

$ paste -d "/" <( awk '/--/{print NR "s/" $0}' file1 ) file2 /dev/null
3s/--/12:00/
6s/--/12:01/
9s/--/12:02/

$ paste -d "/" <( awk '/--/{print NR "s/" $0}' file1 ) file2 /dev/null
| sed -f - file1
x y z
a b c
12:00
x y z
d c f
12:01
x y z
t h y
12:02
