Hello everyone. I wrote this command in the terminal directly and got the desired and expected output - that being the last 50 occurrences of me installing or removing a package with pacman or yay: history | grep -e 'pacman -S\s' -e 'pacman -R\s' -e 'yay -S\s' -e 'yay -R\s' | tail -n 50 > ~/history_installed

I now want to make this runnable as a script for obvious reasons, but when add it to a script and run it I get the following error: /home/user/.bin/check_installed.sh:fc:3: no such event: 1

Here is my entire script:

#!/bin/zsh

{history | grep -e 'pacman -S\s' -e 'pacman -R\s' -e 'yay -S\s' -e 'yay -R\s' | tail -n 50} > ~/history_installed

Note: /home/user/.bin is in my path. Verified by successfully running another script in there from a different location.

Please help me figure this out if you could. I am running zsh with oh-my-zsh. Thanks in advance!

link-batch is a minimalist script that generate symlinks from a list in a text file. Usage :

link-batch.zsh link-list.txt

where link-list.txt contains two columns : the first one for the links and the second one for the targets. Example :

~/.config/kitty	~/myfiles/config/kitty
~/.config/nvim	~/myfiles/config/neovim
~/.config/MuseScore	~/myfiles/config/MuseScore/$HOST
...

The two columns must be separated by a tab.

Shell vars like $HOME or $HOST are evaluated to their values.

Can be used to quickly deploy all home links in a fresh box.

This is working just fine, but it's not finished. However I am not interested in working on it anymore.

I'm sure some of you have absolute monstrosities of sigils (I know I do, in my .zshrc alone). Post them without context, and try and guess what other users's lines are. If you want to provide context or guess, use the markdown editor to spoiler-tag your guesses and explanations!

i'm pretty new to the shell scripting world and not sure, if i should give my scripts a .sh or .bash extension.

not sure what the pros and cons are.

This came out of playing around with curl and the Lemmy API. I wanted a repeatable way to declare a bunch of shell parameters from a json object, so I wrote a jq module! Take a look at the README for examples, or once you install, run

source <( curl 'https://programming.dev/api/v3/community?id=267' | jq -r 'import "shell" as shell; .community_view | shell::param' )

Currently this project only provides a param function, and only supports Bash and Zsh. If I think of other useful helper functions, I may add them to the project.

This uses _ as a default prefix for each parameter. This is so things like {"PATH": "..."} generate typeset _PATH='...' and don't mangle your $PATH, for example. The prefix can be customized by passing in a string: param("mypfx").

Before declaring a 1.0, I'm planning on expanding shell support, and have the function determine how to output using the the $SHELL parameter:

# This does not work (yet!)
eval (curl $URL | jq -r '
  import "shell" as shell;
  "fish" as $SHELL |
  .community_view | param
')

Always up for feedback!

I found this post really helpful to anyone who is using tmux
