Open Terminal Emulator, enter the following commands exactly - su cd /system/bin ln -s /system/xbin/bash-arm bash exit Go into Terminal Emulator Preferences and set the following command line - /system/xbin/bash-arm - Set initial command to - export PATH=/data/local/bin:$PATH; source /sdcard/bash/bashrc Create the bash folder under /sdcard, use EStrongs for that. Create the file bashrc in /sdcard/bash and copy/paste the following into it - Code (Text): #!/system/xbin/bash-arm alias ll="ls -l -a" alias llm="ls -l -a | more" PS1="[\w] \$ " clear echo "Welcome, bash!"
