Shell Programming and Scripting

Dear All,

a.txt
A 1 Z
A 1 ZZ
B 2 Y
B 2 AA

how can i use awk one line to achieve the result:
A Z|ZZ
B Y|AA


Thanks

Use code tags please. Try this:

Code:

awk '{a[$1]=a[$1]?a[$1]"|"$3:$3}END{for (i in a){print i,a[i]}}' file

Code:

awk '{x=$1 FS $2;if(!a[x]){a[x]=$1 FS $NF;next}else{$0=a[x] OFS $NF}}1' OFS=\| file

Hi,
I have a file look likes this :

I would like to print only the following output :

elapsed
----------
0.00
239.91
0.00
----------
239.91


elapsed
----------
0.00
0.00
0.59
----------
0.59

I tryied :

cat filename.txt | awk '{print $4} '
But its not enough since i get all the output under column 4.

Thanks

Code:

awk '$1=="call"{f++}f{print $4}$1=="total"{f--}' file

@yoavbe you highjack this thread ! Please read and respect the forum rules !
Your original thread is https://www.unix.com/shell-programmin...-question.html

Very creative solution Danmero.

1. If the first field of line matches "call" , f is initialized to 1 by f++
2. Evaluates f which is 1, hence true and prints $4
3. Keeps printing $4 till it matches "total", once $1 == total,it decrements f to 0
4. Since f is 0, it no longer evaluates to true, hence comes out of the loop
