If after installing Sql Server on Ubuntu you can’t run sqlcmd getting “sqlcmd: command not found” error then you need to check some things out.
First of all, make sure that have mssql-tools installed. If you are not sure you can simply try to install it:
sudo apt-get install mssql-tools
and if you already have it installed you will get something like this:
Reading package lists... Done Building dependency tree Reading state information... Done mssql-tools is already the newest version (22.214.171.124-1). 0 to upgrade, 0 to newly install, 0 to remove and 242 not to upgrade.
Otherwise, it will be installed on your system. When everything is installed you may still get “sqlcmd: command not found” error when you try to run sqlcmd if you have no proper symlinks created.
First of all, let’s see how this tool is called on your system. It might be called something like sqlcmd-126.96.36.199 or simply sqlcmd but it should be in /opt/mssql-tools/bin/ directory. Let’s see what we have there:
After you get the name of the tool you can create a symlink:
ln -sfn /opt/mssql-tools/bin/sqlcmd /usr/bin/sqlcmd
