How to sort values inside one column?

Hi,

Could someone please help me with this? I have a text file that has fields seperated by comma. The last column in it has multiple values seperated by "|". I need to sort values in the last column seperated by pipe..is there any way I can do this through script?

Sample text file -
Code:
TEST1,ABC,5|4|1|3|2
TEST2,DEF,10|7|25|11|52|19
TEST3,XYZ,5|11|52|1

The output should generate -
Code:
TEST1,ABC,1|2|3|4|5
TEST2,DEF,7|10|11|19|25|52
TEST3,XYZ,1|5|11|52


How can I achieve this? Smilie

Try this:

Code:
$ cat ./sort_fields.ksh
#!/bin/ksh

sort_array()
{
  set -A LOCALARRAY $1

  LOCALARRAY_COUNT=${#LOCALARRAY[*]}

  IDX=0
  TEMP=0
  while (( $IDX < $LOCALARRAY_COUNT ))
  do
    IDX2=`expr $IDX + 1`
    while (( $IDX2 < $LOCALARRAY_COUNT ))
      do
        if (( ${LOCALARRAY[$IDX]} > ${LOCALARRAY[$IDX2]} ))
        then
           TEMP=${LOCALARRAY[$IDX]}
           LOCALARRAY[$IDX]=${LOCALARRAY[$IDX2]}
           LOCALARRAY[$IDX2]=$TEMP
        fi
        IDX2=`expr $IDX2 + 1`
      done
    IDX=`expr $IDX + 1`
  done

 print "${LOCALARRAY[*]}"

}

while read LINE
do
 LINEPT1=${LINE%,*}
 set -A FIELDS $(echo $LINE | cut -d',' -f3 |cut -d'|'  --output-delimiter=' ' -f1-)
 LINEPT2=$(sort_array "${FIELDS[*]}"|cut -d' ' --output-delimiter='|' -f1-)
 print "${LINEPT1},${LINEPT2}"

done < test.dat

exit 0

$ cat ./test.dat
TEST1,ABC,5|4|1|3|2
TEST2,DEF,10|7|25|11|52|19
TEST3,XYZ,5|11|52|1

$ ./sort_fields.ksh
TEST1,ABC,1|2|3|4|5
TEST2,DEF,7|10|11|19|25|52
TEST3,XYZ,1|5|11|52

I still consider myself to definitely be a beginner with awk but your question intrigued me so I worked at it a bit. The following doesn't meet 100% of your requirement but I just can't figure it out from this point.

Code:
$ awk -F, '{split($3,a,"|"); n=asort(a,b); for (i=1; i<=n; i++) sort=sort "|" b[i]; print $1 "," $2 "," sort}' file

input
Code:
TEST1,ABC,5|4|1|3|2
TEST2,DEF,10|7|25|11|52|19
TEST3,XYZ,5|11|52|1

output
Code:
TEST1,ABC,|1|2|3|4|5
TEST2,DEF,|1|2|3|4|5|7|10|11|19|25|52
TEST3,XYZ,|1|2|3|4|5|7|10|11|19|25|52|1|5|11|52

As you can see the problem I'm having is getting the for loop to only include the parts of the array relevant to the current line.

I'm scratching my head for now, but I know I'll figure it out soon Smilie

Should be a simple solution, but stop to merge the lines. Anyone can help to continue it?

Code:
$ awk -F[\,\|] '{for(i=3;i<=NF;i++) {print $1,$2,$i}}' urfile |sort -k1,1n -k3,3n
TEST1 ABC 1
TEST1 ABC 2
TEST1 ABC 3
TEST1 ABC 4
TEST1 ABC 5
TEST2 DEF 7
TEST2 DEF 10
TEST2 DEF 11
TEST2 DEF 19
TEST2 DEF 25
TEST2 DEF 52
TEST3 XYZ 1
TEST3 XYZ 5
TEST3 XYZ 11
TEST3 XYZ 52

then I need merge the lines which $1 is same.

Code:
sortbars() {
  echo "$1"|xargs -d'|' -n1|sort -n|xargs|tr ' ' '|'
}
while IFS=, read cola colb colc; do
  echo "$cola,$colb,$(sortbars $colc)"
done < infile

Code:
TEST1,ABC,1|2|3|4|5
TEST2,DEF,7|10|11|19|25|52
TEST3,XYZ,1|5|11|52

Alternatively:
Code:
sortbars() {
  IFS='|'; for i in $1; do
    echo $i
  done|sort -n|xargs|tr ' ' '|'
}

perl:

Code:
while(<DATA>){
	chomp;
	my @tmp=split(",",$_);
	my @t1=split("[|]",$tmp[2]);
	$tmp[2]=join "|", sort {$a<=>$b} @t1;
	print join ",",@tmp;
	print "\n";
}
__DATA__
TEST1,ABC,5|4|1|3|2
TEST2,DEF,10|7|25|11|52|19
TEST3,XYZ,5|11|52|1
