Ok But
I have a file that has dates like this:
date FINAL_RESULT; 6
date FINAL_RESULT; 3
date FINAL_RESULT; 8
With this command: seira=`cut -f2 -d\; tes.txt` i take the date FINAL RESULTs and i store them on variable seira.then seira look like this: 6 3 8
I want to read seira and make a sum of all results 6+3+8 etc. i don't know how mane records there are in the file. So i want to read seira with the the next loop using while but it doesn 't work. i don't want to use grep or awk. I want to use while and cut but it is wrong. Can yoy help me please
while [ "$seira" != "" -a "$seira" != " " ]
do
sum=0
pros1=`cut -f1 -d \ $seira`
pros2=`cut -f2 -d \" " $seira`
sum=`expr $sum+$pros1`
seira=$pros2
done

sum
sum(1B) SunOS/BSD Compatibility Package Commands sum(1B)
NAME
sum - calculate a checksum for a file
SYNOPSIS
/usr/ucb/sum file...
DESCRIPTION
sum calculates and displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an algorithm which may
yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
been transferred between machines with different-sized ints.
USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWscpu |
+-----------------------------+-----------------------------+
SEE ALSO
sum(1), wc(1), attributes(5), largefile(5)
DIAGNOSTICS
Read error is indistinguishable from EOF on most devices; check the block count.
NOTES
sum and /usr/bin/sum (see sum(1)) return different checksums.
This utility is obsolete.
