从 shell 脚本获取 .bash_profile 失败

从 shell 脚本获取 .bash_profile 失败

通常，我可以使用此命令将 ~/.bash_profile 文件作为 oracle 来获取，但是当我为另一个实例创建了一个名为 test 的新文件时。

#!/bin/bash

# User specific environment and startup programs
# Oracle Settings

# User specific environment and startup programs
if ! [[ "$PATH" =~ "$HOME/.local/bin:$HOME/bin:" ]]
then
    PATH="$HOME/.local/bin:$HOME/bin:$PATH"
fi
#export PATH

# Oracle Settings

export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=/opt/oracle/product/21c/dbhome_1
export ORACLE_SID=agile
export ORA_INVENTORY=/opt/app/oraInventory
export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/OPatch

export DISPLAY="localhost:10.0"
export LC_ALL=C

alias sp='sqlplus / as sysdba'
alias script='cd /u02/scripts/agile'
alias software='cd /u02/software'
alias export='cd /u02/backup/export'

当我在 shell 脚本中引用此代码并执行它时，它会抛出错误 cd: too many parameters。我尝试使用 . (dot) 代替 source。结果相同。

$ source test
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments

当我给出“测试”$ chmod a+x ~/test并将其作为源时，出现字符集错误：

$ ls -ltr test
-rwxr-xr-x. 1 oracle oinstall 724 Oct  6 14:37 test
$ souce test
GLib: Cannot convert message: Could not open converter from “UTF-8” to “AL32UTF8”

在测试文件上添加了 export CHARSET=AL32UTF8 并将其作为源，我得到了与开始时相同的错误：

$ vi test
$ source test
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments

甚至我找到了主要的源代码，但从 root 执行 su - oracle 时也没问题。

$ source .bash_profile
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments
-bash: cd: too many arguments

以 root 身份启动时无错误

[root@ ~]# source ~oracle/test

问题几乎肯定是您对别名的选择不当export='cd /u02/backup/export'- 它会覆盖同名的 shell 内置命令。

特别是，如果你在同一个 shell 中第二次执行该脚本，它将导致如下表达式

export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=/opt/oracle/product/21c/dbhome_1

变得

cd /u02/backup/export ORACLE_BASE=/opt/oracle
cd /u02/backup/export ORACLE_HOME=/opt/oracle/product/21c/dbhome_1

其中cd传递了“太多参数”。

对steeldriver的正确答案做一点补充：请注意，在前三个别名命令中，建议的别名是用黑色打印的。然而，在第四个命令中，export这个词是彩色的。这是第一个线索，表明export在某种程度上是特殊的，正如steeldriver所解释的那样。
