I'm working on a Ubuntu system and currently this is what I'm doing:
if ! which command > /dev/null; then
echo -e "Command not found! Install? (y/n) \c"
read
if "$REPLY" = "y"; then
sudo apt-get install command
fi
fi
Is this what most people would do? Or is there a more elegant solution?
To check if packagename
was installed, type:
dpkg -s <packagename>
You can also use dpkg-query
that has a neater output for your purpose, and accepts wild cards, too.
dpkg-query -l <packagename>
To find what package owns the command
, try:
dpkg -S `which <command>`
