linux - 如何在 Cygwin 中重置 PATH 变量列表

Question

$ echo $PATH
/usr/local/bin:/usr/bin:/cygdrive/c/Program Files (x86)/PC Connectivity Solution:/cygdrive/c/Program Files (x86)/RSA SecurID Token Common:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files (x86)/IBM/Client Access/Emulator:/cygdrive/c/Program Files (x86)/IBM/Client Access/Shared:/cygdrive/c/Program Files (x86)/IBM/Client Access:/cygdrive/c/Program Files (x86)/Enterprise Vault/EVClient:/cygdrive/c/Program Files/Java/jdk1.7.0/bin:/cygdrive/c/apache-maven-3.1.1/bin:/cygdrive/c/Program Files/TortoiseSVN/bin:/cygdrive/c/Program Files (x86)/QuickTime/QTSystem:/cygdrive/c/apache-tomcat-7.0.52/bin:/usr/bin:%HADOOP_HOME%/bin

想要删除一些不需要的值并将上面的整个字符串重置为以下

/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files/Java/jdk1.7.0/bin:/cygdrive/c/apache-maven-3.1.1/bin:/cygdrive/c/Program Files/TortoiseSVN/bin

我该怎么做？请指导。

所有 cygdrive 路径都是由 cygwin 从您的 Windows 路径自动添加的。

此 sed 命令将在 .bashrc 的末尾附加一行以设置您的 PATH:

sed -i '$a\PATH="/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Program Files/Java/jdk1.7.0/bin:/cygdrive/c/apache-maven-3.1.1/bin:/cygdrive/c/Program Files/TortoiseSVN/bin"' .bashrc
