Awker expert, Arranging Data, Pls help!

[hendnov]

Hi guys, I'm quite new in awk, please help.
Here's the input data :
10 AMM/SGML/
20 AMM/CGM/
30 AMM/DATA/
46 IPC/SGML/
65 IPC/TIFF/
12 SSM/SGML/
21 SWPM/SGML/

I just want to sort out SGML directory first, and then the graphic files which is CGM or TIFF. other directory I don't want to print out.

so, expected output should be :
10 AMM/SGML/
46 IPC/SGML/
12 SSM/SGML/
21 SWPM/SGML/

20 AMM/CGM/
65 IPC/TIFF/

thx guys!

A starting point:
awk '
/\/SGML\//{print;next}
/\/(TIFF|CGM)\//{a[i++]=$0}
END{for(j=0;j<i;++j)print a[j]}
' /path/to/input

Hope This Helps, PH.

Hi

Sorting in that SGML-CGM-TIFF order would be abit more ugly. Really needed ?

awk -F / '$2~/SGML|CGM|TIFF/{o[$2]=o[$2] $0 "\n"}END{for(i in o)print o[i]}' /input/file
[gray]# or[/gray]
grep -w "SGML\|CGM\|TIFF" /input/file | sort -t / -k 2

THX guys, for your quick reply..

one more question, how do I capture each string of line data into one string. here's the example :

line 1 :
10 SGML -> $CAPTURE

line 2 :
20 TIFF -> $CAPTURE

so, after reading second line, at the end $CAPTURE is "10 SGML \n 20 TIFF" instead of "20 TIFF"

I know, if integer we can use $CAPTURE += 10, but for sentence or word how do i do that?

THX GUYS
