Atypical “ls” - Habr Edition

Hello!



After yesterday's post about replacing the regular ls with other regular (or not so) utilities, I just could not get past the comments, especially considering that the post soared to the top of the charts and in 18 days it was read by 18k, with a tail of a man. Khabrovsk citizens have given the world many new ways to get rid of ls. I checked them all (but this is not accurate), combed some of them so that they corresponded to the conditions of the problem, and I want to share with you. Enjoy it!

1. dir

Yes, damn it. She completely flew out of my head. And although it is completely different than in DOS, Windows, and even in OS / 2, it performs its functions properly!

Eumorozov and cru5ader reminded me of her

dir -aA ~
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

2. printf

I repent. zsh spoiled me and I thought print was such a utility - a light version of echo, but it turned out to be just the giblets of zsh itself. But iig showed a master class using printf

 printf "%s\n" ~/* ~/.*
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

3. echo

Yes, it's him again ... working through automatic autocompletion. Thank you for this SlavniyTeo

 echo -e 'echo \t\ty\b\b\b\b\b\b\b' | bash -i echo -e 'echo \t\ty\b\b\b\b\b\b\b' | sh -i
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

But zsh users are out of luck, although maybe if you configure it?

3. vim

cru5ader recalled that vim has its own file browser, and since vim is everywhere (well, almost. There is a regular vi on the manjaro and this focus will not work with it) then why not use it?

 vim ~
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

4. rm

Yes! Your eyes do not deceive you. What is the basis of the famous Barmin patch , which scares beginner unixoids, we will use exclusively for peaceful purposes. Thanks POPSuL

 yes "n" | rm -i $HOME/* $HOME/.* 2>&1|grep -o "$HOME[^']*"
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

And cheater

 (echo y; yes n) | rm -ir ~ 2>&1 | sed -E -e "s/(rm:[^']+)|\?//g"
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

5. rsync

But actually, why not? Thank you for this 027

 rsync --list-only ~/
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

6. grep

With a grep, you can not only check e-mail for validity, but also extract files. kashtan404 and

KorDen32 showed that this is within his power (fixed on a more correct option).

 grep -l '.*' ~/* ~/.* 2>/dev/null || grep -L '.*' ~/* ~/.* 2>/dev/null
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

7. file

Want to understand what kind of files are in your hamster? Or maybe just list them out? 027 and POPSuL proved that he could do it.

 file ~/* ~/.*
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

8. stat

File or entire file system status? Not only! There are at least three ways to cook a stat. One even from me.

 stat ~/* ~/.*|grep "/home"|awk '{print $2}'
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

Other by polar_yogi

 stat -c "%A %G:%U %s %x %n" * \.*
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

And the third from iig

 stat *|awk '/File:/{print $2}'
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

9. head

Artyushov - the head! Showed how to use head!

 head -n 0 -v ~/* ~/.*|awk '{print $2}'
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

10. getfacl

The key letter in the name of this utility is “f” and Zoro has proven it!

 getfacl ~/* ~/.* | grep "# file" | awk '{print $3}'
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

11. git

Yes, even Git comrade tork made me work for a hamster!

 git init ~/ ; curr=`pwd`; cd ~ ; git status; rm -rf .git; cd $curr ; curr=''
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

12. cat

Everyone loves cats. But the coolest users of BSD systems! Unfortunately in Linux, cats are of the wrong breed. :-( Uzix boasted of its cat.

 cat ~ |strings |xargs -IX sh -c 'test -e X && echo X'
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

13. lsattr

lsattr is not only a valuable tool for looking at file attributes, but also a list viewer for the files themselves. Neveil showed how to do it.

 lsattr ~/* ~/.* 2>&1 | grep -Po '/.*'
      
      

        
        
        
      

    
        
        
        
      
      

        
        
        
      

    
     

Epilogue

I’ll probably dwell on a damn dozen, but those who are interested can look into the comments of the original post and enjoy, because the “single-liners” in perl, ruby, python, php and even C ++ are left behind.
