Convert rows to columns

I am looking to print the data in columns and after every 3 words it should be a new row.


Quote:
Cat example.out
DATA1
DATA
Inner
DATA2
DATA
OUTER
DATA3
TADA
INNER
DATA
SKYP
INNER
TYRE
DESC
INNER
Code:
 
cat example.out |  awk 'END { for (i = 0; ++i < m;) print _[i];print _[0] }{ _[NR % m] = _[NR % m] x ? _[NR % m] OFS $1 : $1}' m=1| grep -i INNER

Quote:
DATA1 DATA Inner DATA2 DATA OUTER DATA3 TADA INNER DATA SKYP INNER TYRE DESC INNER

I am looking to print in a new line after every 3 words.


Quote:
DATA1 DATA Inner
DATA2 DATA OUTER
DATA3 TADA INNER
DATA SKYP INNER
TYRE DESC INNER

Thank You

This command worked for me :-

Code:
 
awk '{printf("%s",NR%3 ? $0"\t":$0"\n")}' example.out

You can also use the paste command:

Code:
$ paste - - - < file
DATA1	DATA	Inner 
DATA2	DATA	OUTER 
DATA3	TADA	INNER
DATA	SKYP	INNER
TYRE	DESC	INNER

Or xargs:
Code:
$ xargs -n3 < file
DATA1 DATA Inner
DATA2 DATA OUTER
DATA3 TADA INNER
DATA SKYP INNER
TYRE DESC INNER

No cat's were harmed in the making of this post Smilie

Code:
awk 'NR%3==1 {print ""} 1 {printf "%s ",$0}' file

DATA1 DATA Inner
DATA2 DATA OUTER
DATA3 TADA INNER
DATA SKYP INNER
TYRE DESC INNER
