Answer:
Code explained below
Explanation:
Please find the bash shell script to find the values of particle file
Sample input file:
NEUTRON 20.900103
PION- 0.215176
PION- 22.716532
NEUTRON 8.043279
PION+ 1.374297
PION- 0.313350
PION+ 0.167848
Program:
#! /bin/bash
if [ $# != 1 ]
then
echo "Usage: $0 <input file>"
exit
fi
#get the total lines in the file
numParticle=`wc -l $1|cut -d' ' -f1`
echo "Total Species: $numParticle"
echo
echo "Species Information:"
echo
#get the unique elements from file
uniqParticles=`cut -d" " -f1 $1|awk '{print$1}'|sort|uniq`
echo "Name Count Minimum Maximum Average"
echo "----- ----- ------- ------- -------"
#loop the unique elements and do grep for each column values
for i in `echo $uniqParticles`
do
count=`grep -c $i $1`
#find the minimum element value
min=`grep $i $1|awk '{print $2}'|numbound -l`
#find the maximum element value
max=`grep $i $1|awk '{print $2}'|numbound`
#find the average of element value
avg=`grep $i $1|awk '{print $2}'|numaverage`
printf "%-10s %7s %14.6f %14.6f %14.6f\n" "$i" "$count" "$min" "$max" "$avg"
done
Output:
Total Species: 7
Species Information:
Name Count Minimum Maximum Average
----- ----- ------- ------- -------
NEUTRON 2 8.043279 20.900103 14.471691
PION- 3 0.215176 22.716532 7.748353
PION+ 2 0.167848 1.374297 0.771072
