When I tried to upgrade LuLu the firewall with command brew upgrade lulu, I faced this error.
Error: lulu: uninstall script /Applications/LuLu.app/Contents/Resources/LuLu Uni nstaller.app/Contents/MacOS/LuLu Uninstaller does not exist. Then thought of trying to remove/uninstall lulu, then re-install it. So, I ran brew remove --cask lulu using homebrew package manager. But the same error occurred.
I thought maybe it did not upgrade as I did not use --cask in the first command.
Just use $CMD_DURATION to get the time taken running the last command.
To make your prompt give you the elapsed time for every command you run in Terminal, add this function in your Fish config file ~/.config/fish/config.fish.
function fish_prompt; echo "$CMD_DURATION "; end The prompt will be like that.
I hope this helps you. You know someone will benefit from this, share it with him/her, a friend or colleage.
We can use string split like this (string split -r -m1 . $filename).
I use this method in my Fish script function.
function vidfps --description "vidfps <input.mp4>" ffmpeg -i $argv -filter:v fps=fps=24 (string split -r -m1 . $argv)-24fps.mp4 end The above function is located in my ~/.config/fish/config.fish file. So I can use it to convert a video to a 24 frames-per-second video using ffmpeg. the code (string split -r -m1 .
Here is a command with 3 arguments.
myfunc one two "third arg" How to get each argument in Fish script/function.
to get all arguments as one string/text, use $argv. to get first argument, use $argv. to get second argument, use $argv. to get the function name or the script name, use $argv. to the remaining three arguments after two : myfunc one two three four five, use $argv[3..-1] as -1 is the end of arguments.
This error appears in too many cases, for example: when you are trying to ..
upgrade Flutter via flutter upgrade. upgrade a homebrew cask via brew upgrade --cask --greedy. push to GitLab. curl some file from the internet. the errno 54 (error number 54) means “Connection reset by peer”, which basically indicates a generic network connectivity problem. So, It’s a network issue. If your internet is very slow and there are hiccups with network, you will face this error.
Using open command doesn’t fulfil this job. So we need to use another command.
We can use open -a TextEdit filename.ext for example open -a TextEdit pin.svg. This command will open the file in TextEdit program in Mac OS.
We can use another flag with the open command to achieve the same goal. The command is open -e filename so we can use open -e /Users/mbp/Desktop/work/VectorAndClipart/pin.svg to open the pin.svg file in the Mac OS graphical text editor TextEdit.
