An array containing the values of the current environment. The array is indexed by the environment variables, each element being the value of that variable (e.g., ENVIRON["HOME"] might be /home/arnold). Changing
First, all variable assignments specified via the -v option are performed. Next, gawk compiles the program into an internal form. Then, gawk executes the code in the BEGIN block(s) (if any), and then proceeds to read each file named in the ARGV array. If there are no files named on...

If no slashes are given in the first argument, the first argument is assumed to be a variable containing a regular expression. The sub() only changes the first occurrence. The gsub() function is similar to the g option in sed: all occurrence are converted, and not just the first. That ...

You can pass variables by specifying a * instead of a number in the formatting string. $ # same as: awk 'BEGIN{pi = 3.14159; printf "%010.3f\n", pi}' $ awk 'BEGIN{d=10; p=3; pi = 3.14159; printf "%0*.*f\n", d, p, pi}' 000003.142 Passing a variable directly to printf...

The separator specified with the--joinoption is implemented internally asast.literal_eval("'''"+STRING.replace("'", r"\'")+"'''"). If one works hard at it, it is possible to pass values which will cause pyfil to crash; i.e. patterns ending with a backslash. Keep in mind rules...
