If it's just numbers like 1|2|3|4, then

Code:
#!/bin/ksh

IFS="|"
# Read individual lines from inputfile
while read LINE
do
        # Split $LINE apart on IFS into the array CSI
        set -A CSI $LINE

        # Start at column 1.  Column 0 would be that time column
        N=1
        while [ ! -z "${CSI[$N]}" ]
        do
                # If the column is blank, set it to zero
                [ -z "${CS[$N]}" ] && ((CS[$N]=0))
                # Add the number to the column
                ((CS[$N] += CSI[$N]))
                # Add one to N
                ((N++))
        done
done < inputfile

N=1
while [ ! -z "${CS[$N]}" ]
do
        echo "cs$N=${CS[$N]}"
        ((N++))
done

Code:
$ cat >inputfile <<EOF
1|2|3|4
5|6|7|8
9|10|11|12
EOF
$ ./addcol.sh
cs1=18
cs2=21
cs3=24
$

Updated to fit your data better:

Code:
#!/bin/ksh

IFS="|"
# Read individual lines from inputfile
while read TIME LINE
do
        # Split $LINE apart on IFS into the array CSI
        set -A CSI $LINE

        N=0
        while [ ! -z "${CSI[$N]}" ]
        do
                [ -z "${CS[$N]}" ] && ((CS[$N]=0))
                ((CS[$N] += CSI[$N]))
                ((N++))
        done
done < inputfile

N=0
while [ ! -z "${CS[$N]}" ]
do
        echo "cs$N=${CS[$N]}"
        ((N++))
done

...or just do it all in awk then read it once into the shell:

Code:
LINE="`awk -v FS='|' '{ for(N=2; N<=NF; N++) { T[N]+=$N; MAX=N; } }
END { for(N=2; N<=MAX; N++) printf("%s ", T[N]); printf("\n"); }' inputfile`"

set -A CS $LINE

N=0
while [ ! -z "${CS[$N]}" ]
do
        echo "CS$N=${CS[$N]}"
        ((N++))
done

Before I even attempt this, is it possible to grep for a pattern, maybe a partial sentence like "go to page 3", assign that to a variable and then use awk or something to pull out the 3 and assign it to a variable? So first I would have Gotopg = "go to page 3" then page = 3 (9 Replies)

RECVSTATS(8C)															     RECVSTATS(8C)

NAME
recvstats - summarize HylaFAX receive accounting information SYNOPSIS
/usr/sbin/recvstats [ options ] [ files ] DESCRIPTION
recvstats is a command script that prints a summary of the HylaFAX accounting statistics for received facsimile. The statistics can be sorted using one of several keys: the caller's CSI (default), CIDName (CallID2), CIDNumber (CallID1), the communication speed, or the com- munication data format. Statistics are read from the file /var/spool/fax/etc/xferfaxlog unless filenames are specified on the command line. The following table is an example of the output from recvstats (using the default sort key): Sender CIDName CIDNumber Pages Time Pg/min Errs TypRate TypData 61 30:47 2.0 16 9600 1-DMR +13037904674 5 1:34 3.2 2 9600 1-DMH +14159657824 1 1:00 1.0 0 9600 1-DMH +15086636852 2 0:00 2.0 0 9600 1-DMH +15105268781 740 5:47:51 2.1 59 9600 1-DMH +15105287164 20 7:00 2.9 0 9600 1-DMH +15123713545 3 1:19 2.3 0 9600 1-DMH +15123713641 5 1:04 4.6 0 9600 1-DMH +16099211926 3 2:00 1.5 0 9600 1-DMH +17088987617 1 0:18 3.3 0 9600 1-DMH 415 390 6175 22 6:01 3.6 0 9600 1-DMH 415 965 7651 56 34:52 1.6 14 9600 1-DMH 415 973 6723 1 2:09 0.5 0 9600 2-DMR 49 211 161514 1 0:00 1.0 0 9600 2-DMR 8185970503 1 0:28 2.1 0 9600 2-DMR ALDUS CORPORATION ALDUS CO 5551212 3 2:34 1.2 0 9600 1-DMH -------------------------------------------------------------------------------------------------- Total 925 7:19:03 2.1 91 The Sender column shows the caller's TSI (notice that some callers have not setup a TSI). The CIDName column is the received CIDName value for the sender. The CIDNumber column is the received CIDNumber value for the sender. The Pages column is the total number of good pages received. The time column shows the total amount of time spent receiving facsimile from a sender. The Pg/min column displays the average transfer rate. The Errs column indicates how many protocol errors were encountered while receiving facsimile. The TypRate column displays the most common communication speed with which facsimile were received. The TypData column shows the most common data format in which fac- simile data were received. OPTIONS
-age days Show information only for the facsimile received in the last specified number of days. -csi* Sort output by caller's CSI. -cidname Sort output by CIDName -cidnumber Sort output by CIDNumber -format Sort output by data format. -send* Sort output by sender (i.e. caller's CSI). -speed Sort output by signalling rate. -since time Show information only for the facsimile received since the specified time; where time is of the form ``MM/DD/YY HH:MM'' (the date(1) format string %D %H:%M). -end time Show information only for the facsimile received before the specified time; where time is of the same form as since.
