A simple command to run scripts/commands in multiple directories in sequence. Spread is designed to do one thing and do it well.
Using Homebrew:
$ brew install tfogo/tools/spread
Using go:
$ go get github.com/tfogo/spread
$ spread [command] [directories...]
Say we're in a directory A with three subdirectories which all have README.md files:
A
├── dir1
│ └── README.md
├── dir2
│ └── README.md
└── dir3
└── README.md
To append some text to each README.md file, run:
$ spread 'echo text >> README.md'
The first argument to spread is the command to run in each subdirectory.
By default spread will run the command in all the subdirectories of the present working directory. You can specify directories in which to run the command by adding further arguments:
$ spread 'echo text >> README.md' dir1 dir2
A common use is chaining multiple commands based on the exit code of previous commands using &&. For example, running tests then pushing to a git remote:
$ spread 'npm test && git push origin master'
If you need to run a no-op, use an empty string, a colon, or true as the first argument.
$ spread ''
$ spread :
$ spread true
To view the help, run spread without any arguments or pass the --help or -h flags.
