Great sentence! However, Powershell got quite mature. `cat -n` is definetly something you will be able to do in Powershell with a similarly lengthy command.
- caspervonb 9y agoHaven't tried WSL yet but that's an option. Also most if not all of the GNU coreutils are available on Windows.
- colek42 9y agoThe file system performance was horrendous when I last used it for anything serious last fall.
- cube2222 9y agoWhich matters if you have 15k packages from npm to get (been there, done that) but doesn't matter at all when you're programming in Go.
- colek42 8y agoDep/Glide can get pretty slow.
- panopticon 9y agoFile system performance seems great for me, but I've only been seriously using WSL for the last 6 months or so. That being said, there are some major performance issues with how certain programs map memory and, as a result, things like Haskell are an absolute pain to use.
- tome 9y agoI'm using Haskell right now. It's fine.
- AskewEgret 9y agoOf course. Get-Content puts every line of text into the pipeline as a .Net String object with a few additional attributes added on, including ReadCount which is the line number. For example: Get-Content -Path TEXT.TXT | %{"$($_.ReadCount) $($_.Length) $($_.ToUpper())" } For each line of text, this will print the line number, the length of the string, and the string converted into upper case. PowerShell is very wordy, but very powerful.
- Cthulhu_ 9y agoI'm neither a sh nor powershell guru, but, it kinda feels like that Powershell was intended more as a scripting language, less as a commandline language. sh / bash / etc commands are more terse, but harder to read if they're composed into a shell script. I mean I still can't wrap my head around [ being a command / executable usable in conditions.
- brudgers 9y agoThe terseness of Bash etc. is a tradeoff. "cat" is short for "concatenate." It's common use to list a single file is more the exploitation of an ambiguous API than a feature...concatenation of one file is like the sound of one hand clapping. I mean "to display the contents of a file use 'cat filename'" is an example of how *nix terseness makes understanding dependent on oral tradition rather than clear written communication. Even the man page doesn't describe using cat to display the contents of a single file [1]. It is only implied via the stdin example once a person understands the abstract relationship between the terminal and files. [1]: https://linux.die.net/man/1/cat https://linux.die.net/man/1/cat
- AnIdiotOnTheNet 9y agoSince shell languages invariably end up becoming scripting languages (see: Bourne shell and resulting nightmare), Powershell targets being a good tool for both purposes. When scripting and writing documentation, full commandlet names are encouraged: Get-ChildItem | Where-Object { $_.Name.Contains("evidence") } | Remove-Item When using the command line, there are built-in shortcuts (and users may define their own aliases): gci | ?{ $_.name.contains("evidence") } | ri For the convenience of those hopelessly entrenched in Bourne shell, there are some default aliases: ls | ?{ $_.name.contains("evidence") } | rm
- pmarin 9y ago20 years using unix systems and never used cat with arguments. nl(1)
- omaranto 9y agoI agree that nl is better for line numbering, but have you really never used cat with arguments? One of the most common use cases is for concatenating files: cat file1 file2 > combined-file There file1 and file2 are arguments. What do you use cat for?
- pmarin 9y agoI mean flag arguments. sed {} file1 file2 > combined-file
- pjmlp 9y agoDepends, some people do prefer environments that are more welcoming to the Xerox PARC ideas of how a development environment should look like.
