8Recently I moved back to [bash](https://www.gnu.org/software/bash/) as my default shell. 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.
9
10So 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.
11
12I found a nice alternative that emulates [zsh](http://zsh.sourceforge.net/) like autosuggestion and autocomplete so I added the following to my `.bashrc` file.
13
14```bash
15bind "TAB:menu-complete"
16bind "set show-all-if-ambiguous on"
17bind "set completion-ignore-case on"
18bind "set menu-complete-display-prefix on"
19bind '"\e[Z":menu-complete-backward'
20```

22I haven't noticed anything wrong with this and all was working fine until I restarted my machine and then I got this error.

26When 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).
27
28So I added a simple `if [ -t 1 ]` around `bind` statements to avoid running commands that presume the session is interactive when it isn't.
29
30```bash
31if [ -t 1 ]; then
32 bind "TAB:menu-complete"
33 bind "set show-all-if-ambiguous on"
34 bind "set completion-ignore-case on"
35 bind "set menu-complete-display-prefix on"
36 bind '"\e[Z":menu-complete-backward'
37fi
38```

40After logging out and back in the problem was gone.
