retrier.sh

🦔 tool for retry works on shell.

install

Two way:

• copy the context of one source file, and write them into ~/bin/retrier .
• or change the last line exec retrier "$@" to :;, then write the context into /etc/profile.d/retrier.sh, then run exec $SHELL.

demo

ENV='WORKS () { sleep 3 ; cd $RETRIED ; }' retrier WORKS

desc (zh)

它基于 SHell 编写，能对指定的命令自动失败时重试。

依靠元编程简化了重复代码；依靠子命令打包代码； Bash 版依靠 TCO 的 Tail Call 完成不依赖关键字的迭代。
