I experimented with not having persistent shell history, after @simontatham blogged about it.

Good:
- higher threshold for writing long complicated commands
- lower threshold for writing shell scripts instead

Bad:
- writing shell scripts

I've since started experimenting with the Fish shell, and it brings a whole different level to the shell history game. So far I like it.

I've probably tooted about this before, but I don't know why this isn't standard.

It's just so obvious, at least to me. ;)

~ $ type mcd
mcd is a function
mcd () 
{ 
    [[ -n $1 ]] && mkdir "$1" && cd "$1"
}

Should've made this a long time ago:

function ciglob {
    #case-insensitive glob generator
    echo "$*" |while read -N1 c; do
        case "$c" in
            [a-zA-Z])   echo -n "[${c^^}${c,,}]";;
            *)          echo -n "$c"
        esac
    done
}

~ $ ciglob "Hello, world!"
[Hh][Ee][Ll][Ll][Oo], [Ww][Oo][Rr][Ll][Dd]!
~ $ ls -ld $(ciglob documents)
drwxr-xr-x 52 ~~~ ~~~ 20,480 Apr 10 11:45 Documents

(Not the most useful example, but I did have a use case in mind when I wrote it ;)

P.S. (This is a valid way to close a parenthesis. Fight me ;)

@jeeynet Salut, merci pour l'idée, je ne savais pas que c'était possible ! Concernant le script proposé, ce test est bizarre  :

if [ "${1}" ]

Si "${1}" venait à coïncider avec un opérateur de test(1) , vous auriez des surprises. Je suggère ceci à la place :

if [[ $# -gt 0 ]]

ou bien

if [[ -n "$1" ]]

Notes :

• on peut se permettre [[ … ]] car le script utilise Bash;

• vous pouvez enlever les " autour de $1 dans cet exemple mais attention, c'est un cas bien particulier dû au fait que [[ … ]] ne fait pas de “word splitting” sur l'expression fournie).

My master's thesis "Understanding the role of Unix shell in software development and developer experience" is now available online!

Explore how developers use the shell, their emotions towards it, and its impact on developer experience.
