Passing commandline argument to a function


I have 2 ksh scripts.
Script1.ksh contains function definition.

function f1() {

while getopts a:c: args
case $args in
a) ARG1=$OPTARG ;;
c) ARG2=$OPTARG ;;
\?) echo "Error no valid Arguments passed"
echo $ARG1
echo $ARG2
. script1.ksh

sql_query="select * from emp"

f1 -a "ABCD1234" -c $sql_query

When I execute the script2.ksh, I am getting output as ABCD1234 and select
Where I should get the select * from emp.
Can any one please let me know where is the error?

Just use the follows.
f1 -a "ABCD1234" -c "$sql_query"

Here the variable $sql_query is having the string containing the space.
So you should use double quotes like "$sql_query".

Then only it will preserve the white space.
Now I ran the script and got the output as follows

select from emp

Turn off wildcard expansion before you call script1.ksh and use double quotes and you should be fine.


# disable filename substitution.
set -o noglob

. script1.ksh

sql_query="select * from emp"

f1 -a "ABCD1234" -c "$sql_query"

# enable filename substitution.
set +o noglob

sql_query="select * from emp"

f1 -a "ABCD1234" -c "$sql_query"

$ ./script2.ksh
select * from emp
select script1.ksh script2.ksh from emp

Good luck.
