无法运行脚本

我正在运行 Ubuntu 18.04 LTS。

我发现终端使用了该.bashrc文件。我补充道：

export PATH="/home/keaton/scripts/:$PATH"

到该文件，然后在目录中创建一个脚本scripts。简单的脚本是：

echo "Hello World"
echo $(which neqn)
cat $(which neqn)

当我进入终端并运行时，sh intro我得到：

sh: 0: Can't open intro

我已经三次检查目录的路径scripts是否正确输入。我是否输入或配置不正确？

答案1

而不是使用sh尝试使用bash.这对我有用：

$ bash intro
Hello World
/usr/bin/neqn
#! /bin/sh
# Provision of this shell script should not be taken to imply that use of
# GNU eqn with groff -Tascii|-Tlatin1|-Tutf8|-Tcp1047 is supported.

GROFF_RUNTIME="${GROFF_BIN_PATH=/usr/bin}:"
PATH="$GROFF_RUNTIME$PATH"
export PATH
exec eqn -Tascii ${1+"$@"}

# eof

当您调用脚本时，sh您实际上正在使用，bash但它运行在一种模式下，这使得它的行为就像是 Bash 前身的 shell 的更古老版本一样。

摘自man bash： 
 If  bash  is  invoked  with the name sh, it tries to mimic the startup 
 behavior of historical versions of sh as closely as possible, while 
 conforming to the POSIX standard as well.  When invoked as an interactive 
 login shell, or a non-interactive shell with the --login option, it first 
 attempts to read and execute commands from /etc/profile and ~/.profile, 
 in that order. The  --noprofile option may be used to inhibit this 
 behavior.  When invoked as an interactive shell with the name sh, bash 
 looks for the variable ENV, expands its value if it is defined,
 and uses the expanded value as the name of a file to read and execute.  

 Since a shell invoked as sh does not attempt to read and execute  
 commands  from  any  other  startup  files,  the --rcfile  option  has no 
 effect.  A non-interactive shell invoked with the name sh does not 
 attempt to read any other startup files.  When invoked as sh, bash enters 
 posix mode after the startup files are read.
