Home -> Community -> Mailing Lists -> Oracle-L -> RE: DONE script enclosed: shell script to compare nos.
Hi Raja,
I have not been following this thread until now, but the assumption that each minor point number will be two digits rather than one may not be valid. Also, if your objective is to do it entirely in the shell, consider using IFS to avoid the cut as follows.
#!/bin/sh
v1=$1; v2=$2
ifs="$IFS"; IFS=.
set $v1; v1a=$1; v1b=$2; v1c=$3
set $v2; v2a=$1; v2b=$2; v2c=$3
IFS="$ifs"
if [ "0$v1a" -eq "0$v2a" ] ; then
if [ "0$v1b" -eq "0$v2b" ] ; then
if [ "0$v1c" -eq "0$v2c" ] ; then
echo "$v1 is the same as $v2"
elif [ "0$v1c" -lt "0$v2c" ] ; then
echo "$v1 is less than $v2"
else
echo "$v1 is greater than $v2"
fi
elif [ "0$v1b" -lt "0$v2b" ] ; then
echo "$v1 is less than $v2"
else
echo "$v1 is greater than $v2"
fi
elif [ "0$v1a" -lt "0$v2a" ] ; then
echo "$v1 is less than $v2"
else
echo "$v1 is greater than $v2"
fi

Hello every one,
Thanks for the awk script sent before, I could not use ask as some sites dont have awk but have nawk, so my script will fail. So alternatively devised this shell script, which does the job:-
#!/bin/sh
olddir="7.04.03"
olddir1="`echo $olddir| cut -c1 `" olddir2="`echo $olddir| cut -f2 -d"." `" olddir3="`echo $olddir| cut -f3 -d"." `"if [ "$olddir3" = "" ]; then
ver1="`echo $VER| cut -c1 `" ver2="`echo $VER| cut -f2 -d"." `" ver3="`echo $VER| cut -f3 -d"." `"
echo "The $olddir version is greater than $VER version" elif [ "$fullversion" -lt "$fullver" ];then
echo "The $olddir version is less than $VER version" else
echo "Both versions are equal"
fi
Basically I strip away the release nos. like instead of accepting 7.04.03, I accept it as 70403 and then compare and output.
Thanks for help.
Regrads,
Raja
