Is there any convenient way to strip an arbitrary extension from a file name, something à la bash ${i%%.*}? Do I stick to my friend sed?


Nope. fish has a much smaller feature set than bash, relying on external commands:

$ set filename foo.bar.baz
$ set rootname (echo $filename | sed 's/\.[^.]*$//')
$ echo $rootname
foo.bar

Introduction, Nope. fish has a much smaller feature set than bash, relying on external commands: $ set filename foo.bar.baz $ set rootname (echo $filename  Supports Oh My Fish packages, but 100% compatibility is not a goal. Packages using Oh My Fish non-standard extensions like init.fish, uninstall.fish, key_bindings.fish or recursive directories are supported (but strongly frowned upon as fish-shell has canonical alternatives and using Oh My Fish specific extensions create framework lock-in)


If you know the extension (eg _bak, a common usecase) this is possibly more convenient:

for f in (ls *_bak)
    mv $f (basename $f _bak)
end

With the string match function built into fish you can do

set rootname (string match -r "(.*)\.[^\.]*\$" $filename)[2]

The string match returns a list of 2 items. The first is the whole string, and the second one is the first regexp match (the stuff inside the parentheses in the regex). So, we grab the second one with the [2].

Commands, The two lines below behave identically - unlike other shells, fish will output value both times: $fish_color_cwd echo -n (prompt_pwd) set_color normal echo -n ' > ' end For example, to remove the greeting use: Try it out, this is very convenient! You can find those extensions, including prompts, themes and useful  I'd love strict mode to be the default.-x could also be an option to begin, if it's possible for begin to take arguments.I often have individual sections of script with -x disabled if they produce a lot of useless logging, so it'd be nice to control this at a finer level than at process startup.


You can strip off the extension from a filename using the string command:

echo (string split -r -m1 . $filename)[1]

This will split filename at the right-most dot and print the first element of the resulting list. If there is no dot, that list will contain a single element with filename.

If you also need to strip off leading directories, combine it with basename:

echo (basename $filename | string split -r -m1 .)[1]

In this example, string reads its input from stdin rather than being passed the filename as a command line argument.

How do I run a command every login?, dirs - print directory stack · disown - remove a process from the list of jobs · echo - display a line of text · else - execute command if a condition is not met  An oven (microwave or steam-oven) can also be used for heat treatment. The fish can be packed in plastic or put on a small porcelain plate covered with alufoil. For cod loins (2,5x1,5x6cm) on a porcelain plate covered with alufoil the heating time in a steam-oven (convectomate) at 100°C must be 10 minutes.


The fish string command is still the canonical way to handle this. It has some really nice sub commands that haven't been shown in other answers yet.

split lets you split from the right with a max of 1, so that you just get the last extension.

for f in *
    echo (string split -m1 -r '.' "$f")[1]
end

replace lets you use a regex to lop off the extension, defined as the final dot to the end of the string

for f in *
    string replace -r '\.[^\.]*$' '' "$f"
end

man string for more info and some great examples.

fish-shell/fish-shell, It is indeed possible to do this partially, and many other shells do so. But it was felt there are enough serious corner cases that this is a bad idea. Most such issues  Better support for the fish shell including tab completion (Thanks Alberto!) New function extensions(): This allows for modules like python to report that the extensions numpy and scipy are part of the modules. Users can use "module spider numpy" to find which modules provide numpy etc.


Wildcard exclude · Issue #1444 · fish-shell/fish-shell · GitHub, add `string` subcommands to strip a given suffix or prefix #4002. Open for this issue we can discuss whether it is safe to establish a new idiom. Heck, if I know the extension, even basename "${f}" '.jpg' is more convenient! %.* will only remove the last extension; if you want to remove all the extensions, use %%.*. – chepner Apr 26 '18 at 13:20 1 This seems to work way better than the accepted answer.


The fish Shell, A feature I often find myself missing from both bash and fish is the Another interesting use-case is if I want to remove all files in a directory except some: Interestingly, this is basically an extension of the glob command mentioned in #​354. Regex also has convenient means for negation/exclusion. Is it possible a new state order could come down? State officials could pursue other avenues for a stay-at-home order, including legislation or the emergency rule process. The Department of Health Services already kick-started the rulemaking process Thursday by submitting a scope statement outlining its proposal to reinstate parts of the stay-at-home order.


Popular Mechanics, Fish is a *nix shell that offers an alternative to shells like bash and zsh. It derives suggestions from command history, possible commands, This is a very convenient way to change to a previous directory! To remove an alias, enter functions --erase name ( -e ). set extension 'js' set command 'ls *. Note that R code should be if possible “self-sufficient” and not make use of extra functionality provided by the package, so that the data file can also be used without having to load the package or its namespace: it should run as silently as possible and not change the search() path by attaching packages or other environments.
