我的西格温 $HOME /. bashrc 中设定了以下变量

PATH=/bin:/usr/sbin:"/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin":$PATH

问题是,当我登录和.bashrc被执行时, 我得到的重复启动如下:

Dragos@dragos ~
$ echo $PATH | tr  :   
 
/bin
/usr/sbin
/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin
/bin
/usr/sbin
/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin
/usr/local/bin
/usr/bin
/cygdrive/c/WINDOWS
/cygdrive/c/WINDOWS/system32
/cygdrive/c/WINDOWS/System32/Wbem
/cygdrive/c/curl

/usr/bin
/usr/lib/lapack

有人知道是什么原因吗?

这里是我的 < code>. bashrc

$ cat ~/.bashrc    
# base-files version 3.7-1

# To pick up the latest recommended .bashrc content,
# look in /etc/defaults/etc/skel/.bashrc

# Modifying /etc/skel/.bashrc directly will prevent
# setup from updating it.

# The copy in your home directory (~/.bashrc) is yours, please
# feel free to customise it to create a shell
# environment to your liking.  If you feel a change
# would be benificial to all, please feel free to send
# a patch to the cygwin mailing list.

# User dependent .bashrc file

# Shell Options
# #############

# See man bash for more options...

# Don t wait for job termination notification
# set -o notify

# Don t use ^D to exit
# set -o ignoreeof

# Use case-insensitive filename globbing
# shopt -s nocaseglob

# Make bash append rather than overwrite the history on disk
# shopt -s histappend

# When changing directory small typos can be ignored by bash
# for example, cd /vr/lgo/apaache would find /var/log/apache
# shopt -s cdspell


# Completion options
# ##################

# These completion tuning parameters change the default behavior of bash_completion:

# Define to access remotely checked-out files over passwordless ssh for CVS
# COMP_CVS_REMOTE=1

# Define to avoid stripping description in --option=description of  ./configure --help 
# COMP_CONFIGURE_HINTS=1

# Define to avoid flattening internal contents of tar files
# COMP_TAR_INTERNAL_PATHS=1

# If this shell is interactive, turn on programmable completion enhancements.
# Any completions you add in ~/.bash_completion are sourced last.
# case $- in
#   *i*) [[ -f /etc/bash_completion ]] && . /etc/bash_completion ;;
# esac


# History Options
# ###############

# Don t put duplicate lines in the history.
# export HISTCONTROL="ignoredups"

# Ignore some controlling instructions
# export HISTIGNORE="[   ]*:&:bg:fg:exit"

# Whenever displaying the prompt, write the previous line to disk
# export PROMPT_COMMAND="history -a"


# Aliases
# #######

# Some example alias instructions
# If these are enabled they will be used instead of any instructions
# they may mask.  For example, alias rm= rm -i  will mask the rm
# application.  To override the alias instruction use a  before, ie
# 
m will call the real rm not the alias.

# Interactive operation...
# alias rm= rm -i 
# alias cp= cp -i 
# alias mv= mv -i 

# Default to human readable figures
# alias df= df -h 
# alias du= du -h 

# Misc :)
# alias less= less -r                           # raw control characters
# alias whence= type -a                         # where, of a sort
# alias grep= grep --color                      # show differences in colour

# Some shortcuts for different directory listings
alias ls= ls -hF --color=tty                  # classify files in colour
# alias dir= ls --color=auto --format=vertical 
# alias vdir= ls --color=auto --format=long 
# alias ll= ls -l                               # long list
# alias la= ls -A                               # all but . and ..
# alias l= ls -CF                               #

# Functions

# Some example functions
# function settitle() { echo -ne "e]2;$@ae]1;$@a"; }

# Pass in a UNIX path
# Starts notepad++ given a UNIX path argument

# Change filename ending with suffix string to another suffix string

这里是我的 .bash_ profile

$ cat .bash_profile

这里是我的 /etc/bash.bashrc

$ cat /etc/bash.bashrc

$  

# Uncomment to use the terminal colours set in DIR_COLORS
# eval "$(dircolors -b /etc/DIR_COLORS)"

我不修改我的$HOME/.bashrc 命令中的 $PATH, 除了上面的设定 < code> PATH/ code> 命令之外的任何其它地方 。

如果我只输入一条通往美元PATH的路径, 那也会被复制:

PATH="/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin":$PATH

成果包括:

Dragos@dragos ~
$ echo $PATH | tr  :   
 
/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin
/cygdrive/c/Program Files/Java/jdk1.6.0_26/bin
/usr/local/bin

那为什么是复制品?

增编:

I found that I m executing bash twice in my C:cygwinCygwin.bat
The reason is that I have a context menu command to "Open Bash Here" that passes a starting path to C:cygwinCygwin.bat

这是我的C:cygwinCygwin.bat

@echo off

C:

set PATH=%PATH%;C:cygwinin

REM SHELL needed for any screen instances started from bash
set SHELL=/bin/bash
set HOME=C:cygwinhomeDragos
set HOMEDRIVE=C:
set HOMEPATH=cygwinhomeDragos

REM 

if not [%1]==[] (
  C:cygwinincygpath %1 > tmpFile
  set /p startingpath= < tmpFile
  del tmpFile
)

if "%startingpath%"=="" start C:cygwininmintty.exe --icon /Cygwin-Terminal.ico --size 140,50 --exec /bin/bash --login -c "exec /bin/bash -rcfile ~/.bashrc"
if not "%startingpath%"=="" start C:cygwininmintty.exe --icon /Cygwin-Terminal.ico --size 140,50 --exec /bin/bash --login -c "cd  %startingpath% ; exec /bin/bash -rcfile ~/.bashrc"
exit

Figured out that I need to pass --noprofile --norc to bash when calling bash.
Here s the updated C:cygwinCygwin.bat

@echo off

C:

set PATH=%PATH%;C:cygwinin

REM SHELL needed for any screen instances started from bash
set SHELL=/bin/bash
set HOME=C:cygwinhomeDragos
set HOMEDRIVE=C:
set HOMEPATH=cygwinhomeDragos

if not [%1]==[] (
  C:cygwinincygpath %1 > tmpFile
  set /p startingpath= < tmpFile
  del tmpFile
)

if "%startingpath%"=="" start C:cygwininmintty.exe --icon /Cygwin-Terminal.ico --size 140,50 --exec /bin/bash --login
if not "%startingpath%"=="" start C:cygwininmintty.exe --icon /Cygwin-Terminal.ico --size 140,50 --exec /bin/bash --noprofile --norc --login -c "cd  %startingpath% ; exec /bin/bash -rcfile ~/.bashrc"

exit
