bash user can't type the letter 'e'

[ATC]

User can't type the letter 'e' under bash, everything else seems to work OK. If he changes to csh then the terminal works normally.

The problem can be reproduced using su:

[root@*** root]# echo abcdefghijklmnopqrstuvwxyz                
abcdefghijklmnopqrstuvwxyz
[root@*** root]# su - ***
[***@*** ***]$ cho abcdfghijklmnopqrstuvwxyz
bash: cho: command not found

Check the user's .inputrc file.

In this particular case, the file contained a simple spelling error:

[root@*** ***]# cat .inputrc            
et meta-flag on  
set input-meta on
set convert-meta off  
set output-meta on
