awk script to split a file based on the condition - Shell Programming and Scripting

superprogrammer · #1 (**permalink**) 06-13-2005

I have the file with the records like

4234234 US phone
3244234 US cup
2342342 CA phone
8947234 US phone
2389472 CA cup
2348972 US maps
3894234 CA phone

I want the records with (US,phone) as record to be in one file, (Us, cup) in another file and (CA,cup) to be in another
I mean all records with the last two records forming unique pair in the one file itself
Is it possible in awk?

How about this ?

Code:

awk '{ print $0 >> $2$3.txt }' input.txt

where all US cup combination will go into the file UScup.txt, likewise with US phone into USphone.txt et al.

Thanks vino, it worked
I have one more question
If the file is like this
WSRTK10000000000000067839904809787489959595924667889USMNC
WSRTK10000893479900006783990480978748995959592466673CNATT
WSRTK10000893472387462342349899000067839904809787455USAPT
I know that the last 5 characters in each line is my search pattern and my problem remains the same
I want lines containing patterns like USMNC to go to US_MNC etc
Can I extract last few characters of each line in awk?

Ah. The plot thickens !

Is it always the last 5 characters ?

Yes, and each line has equal number of bits, say the pattern starts always after 300 bits in each line and pattern is of 5 bits only

vino · #6 (**permalink**) 06-13-2005

How about this ?

Code:

sed -e 's/\(.*\)\([A-Z][A-Z]\)\([A-Z][A-Z][A-Z]\)/\1 \2 \3/p' list.txt | awk '{ printf $0 >> $2_$3.txt }'

In this case, your output file will contain each line delimited by spaces between the first long stretch of characters then US and then the last 3 characters.

Not 100% right, but close. Have to figure out why..

Here this works fine.

Code:

#! /bin/sh

while read line
do
name=`echo $line | sed -n -e 's/\(.*\)\([A-Z][A-Z]\)\([A-Z][A-Z][A-Z]\)/\2_\3/p'`
echo "$line" >> $name.txt
done < list.txt

Where $name will have the value like US_APT et al.. and list.txt is your input file.
