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 this array does not affect the environment seen by programs which gawk spawns ...
The shell removes the backslash and passes the quoted character on to the command. Single quotes protect everything between the opening and closing quotes. The shell does no interpretation of the quoted text, passing it on verbatim to the command. It is impossible to embed a single quote ...

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...
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...

I found that they differ slightly from my situation. Alternatively, I can directly pass the file. As for solution 3, if you have a file containing the specified format, you can use grep to identify and group the matches, ensuring that they are not a certain character or another specific ...
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...
