I am trying to make a simple thing to make my teammates lives easier. They are constantly copying quote into the command line that are formatted which breaks the command ie: “test“ vs. "test"
It's proved surprisingly annoying to do with:
function damn() { !!:gs/“/" }
or:
alias damn='!!:gs/“/"'
Neither seems to work and keeps giving me either the error
-bash: !!:gs/“/" : No such file or directory
or just:

I must be missing something obvious here.
!
does not work in functions or aliases. According to bash manual:
History expansion is performed immediately after a complete line is read , before the shell breaks it into words.
You can use the builtin fc
command:
[STEP 100] # echo $BASH_VERSION
4.4.19(1)-release
[STEP 101] # alias damn='fc -s “=\" ”=\" '
[STEP 102] # echo “test”
“test”
[STEP 103] # damn
echo "test"
test
[STEP 104] #
For quick referecne, the following is output of help fc
.
fc: fc [-e ename] [-lnr] [first] [last] or fc -s [OLD=NEW] [command]
Display or execute commands from the history list.
fc is used to list or edit and re-execute commands from the history list.
FIRST and LAST can be numbers specifying the range, or FIRST can be a
string, which means the most recent command beginning with that
string.
Options:
-e ENAME select which editor to use. Default is FCEDIT, then EDITOR,
then vi
-l list lines instead of editing
-n omit line numbers when listing
-r reverse the order of the lines (newest listed first)
| With the `fc -s [OLD=NEW ...] [command]' format, COMMAND is
| re-executed after the substitution OLD=NEW is performed.
A useful alias to use with this is r='fc -s', so that typing `r cc'
runs the last command beginning with `cc' and typing `r' re-executes
the last command.
Exit Status:
Returns success or status of executed command; non-zero if an error occurs.
Here is a slightly more general solution using a bash function to wrap the fc
call, if you want to do something to the string beyond substitution.
function damn() {
# Capture the previous command.
cmd=$(fc -ln -1)
# Do whatever you want with cmd here
cmd=$(echo $cmd | sed 's/[“”]/"/g')
# Re-run the command
eval $cmd
}
