A new twist to somewhat common question:
In my interactive script I pre-fill the user input like so:
#process_line.sh
INPUT=$1 # previous value
read -e -p "> " -i "$INPUT" INPUT
To implement command history I call process_line.sh
rlwrap ./process_line.sh $INPUT
Now here's the twist: if I have the "read -e"
option, I can edit the pre-filled input BUT there is no command history, and adversely, I can have command history, courtesy of rlwrap
, without the "read -e"
option, but no pre-filling (that is, "read -i"
doesn't really do anything).
The question, of course, is whether I can have both input pre-fill and editing AND command history at the same time.
Thanks!
Turn off the -e
to read. Then the two readline implementations won't clash.
To get the prompt, you can pass -S "> "
to rlwrap.
