:b:Hi All,
I have a part of a script below:
var1="value1"
awk 'BEGIN {printf("%36s \n ","value1")}'
Instead of directly giving the "value1" , I need to give using "var1" in the above awk statement.
Is this possible?
If so, what is the modified awk command?
Thanks in advance

DESCRIPTION
Lists are sequences of instances of homogeneous data objects. Two distinct levels of calls are needed to represent them in our output
styles. Calls must be made to open and close a list, and for each instance of data in that list, calls must be make to open and close that
instance.
The name given to all calls must be identical, and it is strongly suggested that the name be singular, not plural, as a matter of style and
usage expectations.
A list is a set of one or more instances that appear under the same parent. The instances contain details about a specific object. One can
think of instances as objects or records. A call is needed to open and close the list, while a distinct call is needed to open and close
each instance of the list:
xo_open_list("item");
for (ip = list; ip->i_title; ip++) {
xo_open_instance("item");
xo_emit("{L:Item} '{:name/%s}':0, ip->i_title);
xo_close_instance("item");
}
xo_close_list("item");
Getting the list and instance calls correct is critical to the proper generation of XML and JSON data.
EXAMPLE:
xo_open_list("user");
for (i = 0; i < num_users; i++) {
xo_open_instance("user");
xo_emit("{k:name}:{:uid/%u}:{:gid/%u}:{:home}0,
pw[i].pw_name, pw[i].pw_uid,
pw[i].pw_gid, pw[i].pw_dir);
xo_close_instance("user");
}
xo_close_list("user");
TEXT:
phil:1001:1001:/home/phil
pallavi:1002:1002:/home/pallavi
XML:
<user>
<name>phil</name>
<uid>1001</uid>
<gid>1001</gid>
<home>/home/phil</home>
</user>
<user>
<name>pallavi</name>
<uid>1002</uid>
<gid>1002</gid>
<home>/home/pallavi</home>
</user>
JSON:
user: [
{
"name": "phil",
"uid": 1001,
"gid": 1001,
"home": "/home/phil",
},
{
"name": "pallavi",
"uid": 1002,
"gid": 1002,
"home": "/home/pallavi",
}
]
LEAF LISTS
In contrast to a list of instances, a "leaf list" is list of simple values. To emit a leaf list, call the xo_emit() function using the ""l""
modifier:
for (ip = list; ip->i_title; ip++) {
xo_emit("{Lwc:Item}{l:item}0, ip->i_title);
}
The name of the field must match the name of the leaf list.
In JSON, leaf lists are rendered as arrays of values. In XML, they are rendered as multiple leaf elements.
JSON:
"item": "hammer", "nail"
XML:
<item>hammer</item>
<item>nail</item>
