column Specifies a one-based column index to use to determine which value from a

-i instance Starts parsing with the nth instance of the specified tablename, after the

Description
This command enables the parsing of data from a file containing data output from a command
having using the –sfo parameter. Since the standard formatted output has a well known means
of parsing, this command is intended to be used as a simplified means of having scripts consume
such constructed output files and use this retrieved data in the logic of the scripts being written for
the UEFI Shell.
Examples
The following data is contained in a temporary file (temp.txt):
ShellCommand, "LS"
VolumeInfo, "MikesVolume","400000000","32000000","16000000"
FileInfo, "fs0:/efi/boot/winloader.efi","45670","arsh"
FileInfo, "fs0:/efi/boot/mikesfile.txt","1250","a"
FileInfo, "fs0:/efi/boot/readme.txt","795","a"
To use the index parameter to parse the temp.txt file:
fs0:\> parse temp.txt FileInfo 3 –i 3
795
pause
Pauses the script file execution.
