问题 I am fiddling with Linux command "timeout": it simply stops a long running command after a given seconds. But I would like to timeout not only a command, but a group of commands. I can group command in two way ( ) and { ;} however none of the following works: timeout 1 { sleep 2; echo something; } timeout 1 ( sleep 2; echo something ) How can I do that with grouping? 回答1: timeout is not a shell utility and it does not do shell-style processing. It must be given one single command to execute.

问题 I just installed composer, php, apache etc. on my new SSD. After that I wanted to start coding. I opened my project from another drive in IDE.
