Exec Command

Execute an arbitrary command in each package.

melos exec
# e.g. melos exec -- pub global run tuneup check

The command is executed in a shell. On Windows the shell is cmd.exe and on all other platforms it is sh.

If multiple commands are being executed and no further commands should be executed after a command has failed, connect the commands with &&:

melos exec -- "melos bootstrap && melos run build"

It is important to pass multiple commands as a single string to melos exec, otherwise the shell will pass only the first command to melos exec.

Defines the max concurrency value of how many packages will execute the command in at any one time. Defaults to 5.

# Set a 1 concurrency
melos exec -c 1  -- "dart analyze ."

Whether exec should fail fast and not execute the script in further packages if the script fails in an individual package. Defaults to false.

# Fail fast
melos exec --fail-fast -- "dart analyze ."
