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 '\->'
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 .*
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)
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.
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
You were almost there with your grep solution; let's focus on getting you COLOR again.
Try this:
ls --color=always -ltra | grep '->'
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"
Try file type flag and get rid of the appending @
ls -F /home/usr/foo | grep "@" | sed 's/@//'
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)
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/^/ /'
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
This works good for me however if you will be searching / the filesystem root you will need to omit the proc directory
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 '\->'
