仅显示 tcsh 或 bash 中为符号链接的文件和文件夹

Question

Basically I want do the following:

ls -l[+someflags]

(or by some other means) that will only display files that are symbolic links

so the output would look

-rw-r--r--  1 username grp   size date-time    filename -> somedir
-rw-r--r--  1 username grp   size date-time    filename2 -> somsdfsdf

etc.

For example,

to show only directories I have an alias:

alias  lsd  'ls -l | grep ^d'

I wonder how to display only hidden files or only hidden directories?

I have the following solution, however it doesn't display the output in color:(

ls -ltra | grep '\->'

Answer 1

Find all the symbolic links in a directory:

ls -l `find /usr/bin -maxdepth 1 -type l -print`

For the listing of hidden files:

ls -ald .*

Answer 2

For only "hidden" folders - dot folders, try:

ls -l .**

Yes, the two asterisks are necessary, otherwise you'll also get . and .. in the results.

For symlinks, well, try the symlinks program:

symlinks -v .

(shows all symlinks under current directory)

Answer 3

ls -l | grep lrw 

shows only symlinks (files and directories). Not sure how to get them colorful, though.

ls -lad .* 

shows only hidden files/directories

ls -l | grep drw

shows directories only.

Answer 4

To display JUST the symlinks and what they link to:

find -P . -type l -exec echo -n "{} -> " \; -exec readlink {} \;

To limit to JUST THIS DIR

find -P .  -maxdepth 1 -type l -exec echo -n "{} -> " \; -exec readlink {} \;

Example output (after ln -s /usr/bin moo):

./moo -> /usr/bin

Answer 5

You were almost there with your grep solution; let's focus on getting you COLOR again.

Try this:

ls --color=always -ltra | grep '->'

Answer 6

Improving a little on the accepted answer given by @ChristopheD (coudnt comment on the accepted answer since I dont have enough reputation)

I use an alias

findsymlinks <path> <depth> 

where the alias is

alias findsymlinks "find \!:1 -maxdepth \!:2 -type l -print | xargs ls -l --color=auto" 

Answer 7

尝试使用文件类型标志并摆脱附加的@

ls -F /home/usr/foo | grep "@" | sed 's/@//'

Answer 8

For (t)csh :

ls --color=always -ltra | grep '\->'

(This is simply pbr's answer but with the hyphen escaped.)

Mac OSX

On OSX, ls works differently, so add this to your ~/.cshrc file:

setenv CLICOLOR_FORCE 1   # (equivalent of Linux --color=always)

And then call:

ls -G -ltra | grep '\->'  # (-G is equivalent of ls --color)

Answer 9

For bash:
This provides a nice output.

sl=`find -L /path/to/target -xtype l`; for links in $sl; do ls --color=always -ltra $links; done | sed 's/^/    /'

Answer 10

echo > linklist.found && $(for i in `find /path/to/dir/ -type l`; do echo `ls -d --color=always  $i` `echo " -> "`  $(ls -d --color=always `readlink -f $i`) >> linklist.found; echo >> linklist.found;  done;) && cat linklist.found | more

这对我来说很好，但是，如果您要搜索/文件系统根目录，则需要省略proc目录

Usage: foo $path

Uses current path if none specified.

#!/bin/bash

case "$1" in

    -r)
    find $2 -type l -print | while IFS= read line ; do ls -l --color=always "$line"; done
    ;;

    --help)
    echo 'Usage: foo [-r] [$PATH]'
    echo    
    echo '-r  Recursive'
    ;;


    *)
    ls --color=always -ltra $1 | grep '\->'
