Copy this function to command line, press 'Enter' 'f'' 'Enter' to execute (sentence on the left written only for newbies). Hint 'e|x|v|1..9' in front of displayed last modified file name means: "Press 'e' for edit,'x' for execute,'v' for view or a digit-key '1..9' to touch one file from the recent files list to be last modified" and suggested (hidden files are listed too, else remove 'a' from 'ls -tarp' statement if not intended).
If you find this function useful you can then rename it if needed and append or include into your ~/.bashrc config script. With the command
$ . ~/.bashrc
the function then can be made immediately available.
In the body of the function modifications can be made, i.e. replaced joe editor command or added new option into case statement, for example 'o) exo-open $h;;' command for opening file with default application - or something else (here could not be added since the function would exceed 255 chars).
To cancel execution of function started is no need to press Ctrl-C - if the mind changed and want to leave simple Enter-press is enough. Once defined, this function can with
$ typeset -f f
command be displayed in easy readable form
Clean output, if used in scripts:
$ GET checkip.dyndns.org|grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}'
or
$ GET icanhazip.com
Returns the '$1'th Fibonacci number.
eh stands for Edit History
.
Frequently, I'll mistype a command, and then step back through my history and correct the command. As a result, both the correct and incorrect commands are in my history file. I wanted a simple way to remove the incorrect command so I don't run it by mistake.
.
When running this function, first the ~/bash_history file is updated, then you edit the file in vi, and then the saved history file is loaded back into memory for current usage.
.
while in vi, remember that `Shift-G` sends you to the bottom of the file, and `dd` removes a line.
.
this command is different than bash built-in `fc` because it does not run the command after editing.
