I was previously using [fish](https://fishshell.com/) and got used to the cool features it has. But, regardless of that, I wanted to move to a more standard shell because I was hopping back and forth with exporting variables and stuff like that which got pretty annoying. + +So I embarked on a mission to make [bash](https://www.gnu.org/software/bash/) more like [fish](https://fishshell.com/) and in the process found that I really missed autosuggest with TAB on changing directories. + +I found a nice alternative that emulates [zsh](http://zsh.sourceforge.net/) like autosuggestion and autocomplete so I added the following to my `.bashrc` file. + +```bash +bind "TAB:menu-complete" +bind "set show-all-if-ambiguous on" +bind "set completion-ignore-case on" +bind "set menu-complete-display-prefix on" +bind '"\e[Z":menu-complete-backward' +``` + +I haven't noticed anything wrong with this and all was working fine until I restarted my machine and then I got this error. + +![Profile bind error](/profile-bind-error/error.jpg) + +When I pressed OK, I got into the [Gnome shell](https://wiki.gnome.org/Projects/GnomeShell) and all was working fine, but the error was still bugging me. I started looking for the reason why this is happening and found a solution to this error on [Remote SSH Commands - bash bind warning: line editing not enabled](https://superuser.com/a/892682). + +So I added a simple `if [ -t 1 ]` around `bind` statements to avoid running commands that presume the session is interactive when it isn't. + +```bash +if [ -t 1 ]; then + bind "TAB:menu-complete" + bind "set show-all-if-ambiguous on" + bind "set completion-ignore-case on" + bind "set menu-complete-display-prefix on" + bind '"\e[Z":menu-complete-backward' +fi +``` + +After logging out and back in the problem was gone. -- cgit v1.2.3
