Got back to use windows…
Use putty ssh to Unix server.
Tab completion, up-down arrow history are not working. I thought the putty configuration is not correct. One hour tuning the config, not working. Then I realized maybe the shell is not bash…
Wtf ksh is… Ancient shell language.
Uname gives AIX… No wonder. IBM machine.
Now the solution is clear. “chsh” to find the available shells. Luckily bash is available in “/use/bin/bash”. Add “/usr/bin/bash” to the first line of ~/.profile.
I am expecting more troubles using windows and AIX…
