shell - 在远程节点执行命令

概要

shell模块处理带有一串空格分隔的参数的命令。shell模块和command非常相似，但是它是通过shell/bin/sh来远程执行的。

案例

# Execute the command in remote shell; stdout goes to the specified
# file on the remote.
- shell: somescript.sh >> somelog.txt

# Change the working directory to somedir/ before executing the command.
- shell: somescript.sh >> somelog.txt chdir=somedir/

# You can also use the 'args' form to provide the options. This command
# will change the working directory to somedir/ and will only run when
# somedir/somelog.txt doesn't exist.
- shell: somescript.sh >> somelog.txt
  args:
    chdir: somedir/
    creates: somelog.txt

# Run a command that uses non-posix shell-isms (in this example /bin/sh
# doesn't handle redirection and wildcards together but bash does)
- shell: cat < /tmp/*txt
  args:
    executable: /bin/bash
