I have,
my.sh
while IFS= read -r line ; do
v1="$line";
t1=`echo $line | awk -F= '{print $2}'`
echo "$t1"
done < $1
sample.txt
say=hello
test=0 0/15 * * * ?
logs=valuelogs
Output :
[root@centos gen]# ./my.sh test.txt
hello
0 0/15 hello.txt 2.txt tmp.log my.sh sample.txt test.sh test.txt hello.txt
2.txt tmp.log my.sh sample.txt test.sh test.txt hello.txt 2.txt tmp.log
my.sh sample.txt test.sh test.txt ?
valuelogs
Here we get bad output due to executed command like echo *
& its give list of file on current directory as output.
Is there any alternative solution for same ?
linux bash shell-script centos

The problem is in the echo $line
inside the back quotes. Double quote the variable to prevent wildcard expansion:
t1=`echo "$line" | awk -F= '{print $2}'`
Thanks Bro, It's work for me

You can rewrite your shell script as
awk -F= '{print $2}' "$1"
and avoid all the shell handling entirely (apart from the single quotes here and the $1
parameter expansion which you want anyway); or even as an AWK script
#!/usr/bin/awk -f
BEGIN { FS="=" }
{ print $2 }
