I read various answers on similar topic, but I still can't deal with my problem. Namely, on the remote computer I have a.bashrc file with a bunch of custom made functions. I would like to check if that function exists in that file. Just to add that the script constantly reports that there is a specified function on the remote computer even though it is not. This is what I have done so far:
echo "Enter IP addres of the remote PC [def host@XX.XX.XX.XX]"
read ip
ip=${ip:-host@XX.XX.XX.XX}
$(ssh $ip "[ '$(type -t $1)' = function ]")
if [ $? -eq 0 ]; then
echo "function exist"
else
echo 'function doesnt exist'
fi
$(...)
is expanded localy inside "
quotes. Reseach difference between single and double quotes.
the_function_you_want_to_check=something
ssh "$ip" '[ "$(type -t "'$the_function_you_want_to_check'")" = function ]'
Do not use $?
. Just:
if ssh stuff...; then
echo yes
else
echo no
fi
Thank you for your prompt response. Please note that $1 is actually the first parameter of the bash functions that I run on my local computer. Now, the change you suggested reports that there is no function on the remote computer even though it exists. More complete function that I run on the local machine is:
appendFunction_to_remotePC(){
echo "Enter the IP addres of the PC [def host@XX.XX.XX.XX]"
read ip
ip=${ip:-host@XX.XX.XX.XX}
if ssh "$ip" '[ "$(type -t "'$1'")" = function ]'; then
echo yes
else
echo no
fi
}
I call the function on the local computer in the usual way:
$ appendFunction_to_remotePC "test"
