如何在bash --login -i上更改bash中的目录

Question

I am using Cygwin and wish to run it with diff params so I can change dir as soon as I launch in Windows.

For example

bash --login -i ; cd /

or

bash --login -i ; cd /tmp

but the cd does not work, how can I pass a change directory to

bash --login -i

FYI I can't put the cd in .bash, it has to be passed in

tried this with no luck

bash --login -i -s cd /tmp;

Answer 1

One hack is to use -c to change the directory, then immediately start a new shell in place of the first one. The working directory is inherited. Note that any shell (that supports exec ) could be used to start the new process; once the working directory has been changed, then you can start the interactive login instance of bash .

bash -c "cd /tmp; exec bash --login -i"

I use .bashrc and .bash_logout to recover previous locations. In .bash_logout I store the current directory in a file:

if [ -d ~/.recent-locations ]; then
    pwd > ~/.recent-locations/locus-$RANDOM
fi

and in .bashrc I consume the stored locations:

if [ -d .recent-locations ]; then
    for x in $(ls .recent-locations); do
        dstdir=$(cat .recent-locations/$x)
        rm .recent-locations/$x
        cd $dstdir
        break
    done
fi

For this to work you need to logout explicitly using Ctrl-D or logout ; on the other hand if you don't want to record your location you simply shut down the terminal window via the window manager.

ok so I found a solution to what I needed. in Cygwin .bashrc I put

"$OLDPWD" and it will automatically switch me to the last directory I was in Windows before forks Cygin,

Hopefully helps others,
