我必须检查当前在 Linux 中执行的脚本数量，我必须根据这些数量决定是否再次运行脚本。问题是类路径太长，所以在执行时ps -ef我没有得到完整的路径，只有其中的一部分。
例如：

那么如何检索所需的信息呢？
要获得完整的输出，您可以ww在命令后添加：
ps -ef ww
然后，输出中的行将不会被切断。
我经常在脚本中使用它来确保输出与正在运行的脚本完全匹配。
来自ps -ef：
jacob 11173 5876 0 apr19 ? 00:00:08 /usr/bin/unity-scope-
而说ps -ef ww：
jacob 11173 5876 0 apr19 ? Sl 0:08 /usr/bin/unity-scope-loader applications/applications.scope applications/scopes.scope commands.scope
