C# under Linux, Process.Start() exception of “No such file or directory”

由 蓝咒 提交于 2021-02-20 06:11:02
问题 I am having trouble calling a program with the Process class to start a program. The hierarchy to the executable is in under the bin directory while the current working directory needs to be under the lib directory. /project /bin a.out (this is what I need to call) /lib (this is where I need to be in order for a.out to work) I have set the WorkingDirectory = "path/lib" and the "FileName = "../bin/a.out" . However I am getting an error of: Unhandled Exception: System.ComponentModel

Why does the sys_read system call end when it detects a new line?

问题 I'm a beginner in assembly (using nasm). I'm learning assembly through a college course. I'm trying to understand the behavior of the sys_read linux system call when it's invoked. Specifically, sys_read stops when it reads a new line or line feed . According to what I've been taught, this is true. This online tutorial article also affirms the fact/claim. When sys_read detects a linefeed, control returns to the program and the users input is located at the memory address you passed in ECX. I

安装 Oracle 12cR1 RAC on Linux 7 本文介绍如何在 Oracle Linux 7 上安装 2 节点 Oracle 12cR1 Real Application Cluster （ RAC ）。通过使用共享存储创建 2 个虚拟机，在 Oracle Virtual Box 上进行了此安装。我使用的 OS 平台是 Oracle Enterprise Linux 7 ， Oracle GI 和 RDBMS 版本是 12.1.0.2 。相同的安装指南也适用于 Redhat Linux 7 。 如果 RAC 设置中有超过 2 个节点，安装步骤是相同的。 可以通过以下链接找到 12c RAC 安装的官方文档。 http://docs.oracle.com/database/121/CWLIN/toc.htm Oracle RAC 12c 版本最好配合 Oracle Linux 7 进行安装 Oracle RAC 11.2.04 版本最好配合 Oracle Linux 6 进行安装 前置条件： 通过安装 Oracle Linux 7 来准备所有节点。所有节点上都有私有连接和共享存储。例如，我有 3 个磁盘（每个 2G 大小）用于 CRS 磁盘组用来存储 OCR 和 Voting ，以及 1 个磁盘（ 4G ）用于 DATA 磁盘组来存储数据库。 在示例里面，我们有 2

问题 How can i strip the HTML from document between and including the <...> tags in a HTML document using C?

问题 I have to perform some necessary steps before installing my package, such as taking back up of previous datastore snapshot. For that purpose I'm using a %pre script as follows. %pre #!/bin/sh -------- -------- stamp=`date +%Y%m%d%H%M%S` echo ${stamp} ------------- ------------- The output is as follows: 20161103123325OURCE It is printing some random characters along with date. "OURCE" is not present anywhere in my spec file. The same script works perfectly as standalone. The platform is

Linux常用命令总结

由 孤人 提交于 2021-02-20 04:53:53
一、cd命令(changeDirectory) 1. 命令语法：cd [目录名] -- 说明：切换当前目录至dirName 2. 进入主要目录：cd / 3. 进入"家"目录：cd ~ 4. 进入上一次工作路径：cd - 5. 把上个命令的参数作为cd参数使用：cd !$ 二、pwd命令 -- 查看当前工作目录路径 1. 查看当前路径：pwd 2. 查看软链接的实际路径：pwd -P 三、ls命令（list） 1. ls 命令不仅可以查看linux文件夹包含的文件，而且可以查看文件权限(包括目录、文件夹、文件权限)查看目录信息等等 2. 常用参数搭配： ① ls -a 列出目录所有文件，包含以.开始的隐藏文件 ② ls -A 列出除.及..的其它文件 ③ ls -r 反序排列 ④ ls -t 以文件修改时间排序 ⑤ ls -S 以文件大小排序 ⑥ ls -h 以易读大小显示 ⑦ ls -l 除了文件名之外，还将文件的权限、所有者、文件大小等信息详细列出来 3. 例： ① 按易读方式按时间反序排序，并显示文件详细信息： ls -lhrt ② 按大小反序显示文件详细信息： ls -lrS ③ 列出当前目录中所有以“t”开头的目录的详细内容： ls -l t* ④ 列出文件绝对路径（不包含隐藏文件）： ls | sed "s:^:`pwd`/:" ⑤ 列出文件绝对路径（包含隐藏文件）：
