android - Customize adb prompt -


how can reduce length of path printed before prompt of shell opened adb shell? problem is long can no longer see commands because doesn't break line automatically. prefer name of current directory or abstract code example.

sh -v on android phone gives me

you change ps1 prompt smaller line:

ps1="> "

but it'd better instead increase width of window like:

columns=150
