pipe and paste

forumbaba · 11-08-2012, 11:05 PM

Hi I want to combine the output of two commands in this form

awk 'Complex command' file1 | awk ' Different complex command' file2

but i want the ouptuts on the same line

another option might be
awk 'Complex command' file1 | paste < (` awk ' Different complex command' file2`)
but neither is working

any ideas ?
Thanks

Well it depends what 'Complex command' is. Is 'file2' a result of processing 'file1'?

Maybe something like this might be what you want?
cat 'file1' | awk 'Complex command' | awk ' Different complex command' > 'file2'

Hi ,
Thanks but thats not what i want ,
I m trying to show the output of two entirely independent awk command on the same line

cat file | awk command
is almosst the same as awk command file, but needs more resources.
Probably you can do the following:
awk command1 file1 > result1
awk command2 file2 > result2
paste result1 result2

I think you want the two commands to run in a group and redirect the output to a file.

Code:

{ awk -f awkscript1 file1; awk -f awkscript2 file2; } >results

You could redirect the output on the first command with > and append on the second command with >>.

Another option is to append to the file from inside your awk scripts.

Or maybe using process substitution:

Code:

paste <(awk 'statements' file1) <(awk 'statements' file2) > result

When I do this, I get the following error:
Missing name for redirect

When I do this it gives me the following error:

{: Command not found.

may be this would help, my actual command is something like this

1st command : awk '{ print $1, $2 }' file1 | program3

2nd command : awk '( print $2, $3 }' file2 | program3

program 3 is a script that takes input and performs certain calculations and produces output

replica9000 · 11-09-2012, 12:14 PM

How about:

awk '{ printf $1, $2 }' file1 | program3 && awk '( print $2, $3 }' file2 | program3

Hi ,
This produces the output one after the other:

AA
BB

but I want them side by side :
AA BB

Did you use printf instead of print in the first awk? If it's still not side by side with that, your program3 might be causing it.

When I use printf it prints only the output of the second command

Which shell are you using? Also I didn't know you wanted the outputs to be displayed in different columns.
