得到错误“:找不到命令"；尝试运行shell脚本时 [英] Getting error ": command not found" when trying to run shell script

问题描述

我有一个正在尝试运行的脚本，但是每当我尝试运行该脚本时，都会出现错误:not found".这是我尝试修复的方法:

1. 确保hashbang是正确的#！/bin/bash"
2. 在文件上运行dos2unix
3. 以scriptname.sh，./scriptname.sh和/bin/bash scriptname.sh运行脚本
4. chmod 755脚本名.sh

我仍然无法运行该脚本.任何帮助深表感谢！

解决方案

这是由回车引起的.以下是 bash标签Wiki 的摘录:

1. 检查您的脚本或数据是否具有DOS样式的行尾字符

   • 使用 cat -v yourfile 或 echo"$ yourvariable" |cat -v .

     DOS回车符将在每行后显示为 ^ M .

     如果找到它们，请使用 dos2unix (又名 fromdos )或 tr -d'\ r'

确保检查所有数据，而不仅仅是脚本本身.

I have a script that I'm trying to run but I just get the error ": command not found" whenever I try to run it. Here's what I've tried to do to fix it:

1. Made sure the hashbang is correct "#!/bin/bash"
2. Run dos2unix on the file
3. Run the script as scriptname.sh, ./scriptname.sh, and /bin/bash scriptname.sh
4. chmod 755 scriptname.sh

I still am unable to run the script. Any help is much appreciated!

解决方案

This is caused by carriage returns. Here's the excerpt from the bash tag wiki:

1. Check whether your script or data has DOS style end-of-line characters

   • Use cat -v yourfile or echo "$yourvariable" | cat -v .

     DOS carriage returns will show up as ^M after each line.

     If you find them, delete them using dos2unix (a.k.a. fromdos) or tr -d '\r'

Make sure to check all your data, and not just the script itself.
