awk Built-in Variables ARGV, ARGC - Array of Command Line Arguments
Example
Command line arguments passed to awk are stored in the internal array ARGV of ARGC elements. The first element of the array is the program name. For example:
awk 'BEGIN {
for (i = 0; i < ARGC; ++i) {
printf "ARGV[%d]=\"%s\"\n", i, ARGV[i]
}
}' arg1 arg2 arg3
produces:
ARGV[0]="awk"
ARGV[1]="arg1"
ARGV[2]="arg2"
ARGV[3]="arg3"
