access shell $HISTCMD in file name template

[andykais]

Hi, I am trying to use this plugin to map command output to a fzf interface that shows commands and their outputs side-by-side. To accomplish this, I need to be able to record individual files with a file name I can look up that includes the $HISTCMD. This will let me use commands like fc -lr

10025  fc -l
10024  history -h
10023  history --help
10022  history --helkp
10021  echo "\!"

to map history command numbers to their respective output files. I can then map that to a command log file from this plugin and tie the two together with fzf
