Checking for installed packages and if not found install

yum check if package is installed
check if a package installed
linux check if package is installed
check if a package is installed in bash
dnf check if package is installed
debian check if package is installed bash
python check if apt package is installed
check if sshpass is installed

I need to check for installed packages and if not installed install them.

Example for RHEL, CentOS, Fedora:

rpm -qa | grep glibc-static

How do I do a check in BASH?

Do I do something like?

if [ "$(rpm -qa | grep glibc-static)" != "" ] ; then

And what do I need to use for other distributions? apt-get?

Try the following code :

if ! rpm -qa | grep -qw glibc-static; then
    yum install glibc-static

or shorter :

rpm -qa | grep -qw glibc-static || yum install glibc-static

For debian likes :

dpkg -l | grep -qw package || apt-get install package

For archlinux :

pacman -Qq | grep -qw package || pacman -S package

Install a list of packages only if they aren't already installed, apt-get will fairly silently skip over any package that is installed already so I'm not sure why it needs to get special treatment? ie: root@bun:~# apt-get -y install vlc  I've found all solutions above can produce a false positive if a package is installed and then removed yet the installation package remains on the system. To replicate: Install package apt-get install curl Remove package apt-get remove curl. Now test above answers. The following command seems to solve this condition:

Based on @GillesQuenot and @Kidbulra answers, here's an example how to loop over multiple packages, and install if missing:

packageList="git gcc python-devel"

for packageName in $packageList; do
  rpm --quiet --query $packageName || sudo yum install -y $packageName

How To Find If A Package Is Installed Or Not In Linux And Unix, Find if a package is installed or not using “has” utility​​ The “has” utility will check the presence of various command line tools on the path and also reports their installed version. Now check if a package is available or not like below. If you see the tick mark (✔), the package is installed. Check and list installed packages with yum command From the dnf/yum man page : The list command dumps lists of packages depending on the packages’ relation to the system. A package is installed if it is present in the RPMDB, and it is available if it is not installed but it is present in a repository that DNF knows about.

if [ $(yum list installed | cut -f1 -d" " | grep --extended '^full name of package being checked$' | wc -l) -eq 1 ]; then
  echo "installed";
  echo "missing"

I use this because it returns installed / missing without relying on an error state (which can cause problems in scripts taking a "no tolerance" approach to errors via

set -o errexit

for example)

  • Hi all, I was using this code in something else and found that this does not differentiate partial matches. in my case (RedHat) I had a package file-libs installed but not file which was what I wanted; when I put rpm -qa | grep -qw file || yum install -y file, then file didn't install. The best solution is not to use grep at all. Just use something like this: rpm --quiet --query file || yum install -y file
