I have a variable in bash let say,
val="cmd arg1 arg2"
I want to split into two parts such one part is command and other part will be all the arguments (i.e. $0 & $*). How can I do this?
Sample cases it should work in:
val="/c/Program\ Files/Oracle/VirtualBox/vBoxManage.exe --help -ds"
val="'/c/Program Files/Oracle/VirtualBox/vBoxManage.exe' --help -ds"
val='"/c/Program Files/Oracle/VirtualBox/vBoxManage.exe" --help -ds'
val="../run dsa"
val="/fdfds/fds fds"
You can try something like:
while read -r val
do
echo "The input val is:==$val=="
declare -a 'arr=('"$val"')'
cmd=${arr[0]}
echo "Command is: ==$cmd=="
unset arr[0]
for arg in "${arr[@]}"
do
echo " argument is: ==$arg=="
done
echo
done <<EOF
cmd arg1 arg2
cmd "arg1 1" "arg2 2"
"../so me/cmd md" arg1 arg2
"../so me/cmd md" arg1 "arg2 2"
EOF
it prints
The input val is:==cmd arg1 arg2==
Command is: ==cmd==
argument is: ==arg1==
argument is: ==arg2==
The input val is:==cmd "arg1 1" "arg2 2"==
Command is: ==cmd==
argument is: ==arg1 1==
argument is: ==arg2 2==
The input val is:=="../so me/cmd md" arg1 arg2==
Command is: ==../so me/cmd md==
argument is: ==arg1==
argument is: ==arg2==
The input val is:=="../so me/cmd md" arg1 "arg2 2"==
Command is: ==../so me/cmd md==
argument is: ==arg1==
argument is: ==arg2 2==
e.g.
val='"/c/Program Files/Oracle/VirtualBox/vBoxManage.exe" --help'
declare -a 'arr=('"$val"')'
cmd=${arr[0]}
unset arr[0]
args="${arr[@]}"
echo "cmd:==$cmd== args:==$args=="
prints
cmd:==/c/Program Files/Oracle/VirtualBox/vBoxManage.exe== args:==--help==
