Execute relative path executable in bash script
提问by Huckle
I googled for this senario, but it is flooded with results on how to turn a relative path into an absolute one (which would work, but I feel there is an easier way)
我在谷歌上搜索了这个 senario，但是关于如何将相对路径变成绝对路径的结果充斥着（这会起作用，但我觉得有一种更简单的方法）
I have the following scenario:
我有以下场景：
$ls ../
executable1 dir1
$
$ls
shellscript1
$
$cat ./shellscript1
#!/bin/bash
#Run executable1, which I know is one dir up towards root
../executable1 arg1 arg2 arg3 etc
exit 0
#----End Of Script----
$
$./shellscript1
./shellscript1: line 3: ../executable1: No such file or directory
Essentially I need to call an executable with a relative path from a bash script. It works fine in a bash shell, but in a script it fails to resolve the path. I have verified the working directory is what I expect it to be (i.g., dir1). Is there some callor execlike command I need in front of it? I tried sh ../executable1but of course bash baffs at the executable.
本质上，我需要使用来自 bash 脚本的相对路径调用可执行文件。它在 bash shell 中工作正常，但在脚本中它无法解析路径。我已经验证了工作目录是我所期望的（ig，dir1）。在它前面有我需要的一些call或exec类似的命令吗？我试过，sh ../executable1但当然 bash baffs 可执行文件。

I just tested this, it is based on your information and seems to work just fine.
我刚刚测试了这个，它基于您的信息，似乎工作得很好。
$ ls ../
dir1 executable1 executable1.c
$
$ cat ../executable1.c
#include <stdio.h>
int main(int argc, char ** argv) {
while (*argv) {printf ("<%s> ",*argv++);}
printf("\n");
return 0;
}
$ cat ./shellscript1
$
#!/bin/bash
#Run executable1, which I know is up dir up towards root
../executable1 arg1 arg2 arg3 etc
exit 0
#----End Of Script----
$
$ ./shellscript1
<../executable1> <arg1> <arg2> <arg3> <etc>
$
$ ls -l ../ ./

Could be due to permissions on ..or ../executable1
可能是由于权限..或../executable1
user executing ./shellscriptshould have execute permissions on ..AND ../executable1. Does he?
执行的用户./shellscript应该对..AND具有执行权限../executable1。他吗？
