How to list all symlinks in a Linux directory
To list only the symbolic links on a Linux filesystem, use ls and grep as shown below. This will easily do this for you.
ubuntu ~/Documents $ ls -hula /lib | grep "\->" lrwxrwxrwx 1 root root 21 Feb 4 02:48 cpp -> /etc/alternatives/cpp lrwxrwxrwx 1 root root 20 Feb 4 02:48 ld-linux.so.2 -> /lib32/ld-linux.so.2 lrwxrwxrwx 1 root root 22 Feb 4 02:48 libcryptsetup.so.4 -> libcryptsetup.so.4.5.0 lrwxrwxrwx 1 root root 17 Feb 4 02:48 libip4tc.so.0 -> libip4tc.so.0.1.0 lrwxrwxrwx 1 root root 17 Feb 4 02:48 libip6tc.so.0 -> libip6tc.so.0.1.0 lrwxrwxrwx 1 root root 16 Feb 4 02:48 libiptc.so.0 -> libiptc.so.0.0.0 lrwxrwxrwx 1 root root 20 Feb 4 02:48 libxtables.so.10 -> libxtables.so.10.0.0 |
Another way is to use this trick.
ubuntu ~/Documents $ ls -hula /lib | grep ^l lrwxrwxrwx 1 root root 21 Feb 4 02:48 cpp -> /etc/alternatives/cpp lrwxrwxrwx 1 root root 20 Feb 4 02:48 ld-linux.so.2 -> /lib32/ld-linux.so.2 lrwxrwxrwx 1 root root 22 Feb 4 02:48 libcryptsetup.so.4 -> libcryptsetup.so.4.5.0 lrwxrwxrwx 1 root root 17 Feb 4 02:48 libip4tc.so.0 -> libip4tc.so.0.1.0 lrwxrwxrwx 1 root root 17 Feb 4 02:48 libip6tc.so.0 -> libip6tc.so.0.1.0 lrwxrwxrwx 1 root root 16 Feb 4 02:48 libiptc.so.0 -> libiptc.so.0.0.0 lrwxrwxrwx 1 root root 20 Feb 4 02:48 libxtables.so.10 -> libxtables.so.10.0.0 |
How to list only directories in a Linux filesystem.
ubuntu ~/Documents $ ls -hula /var/log | grep ^d drwxrwxr-x 14 root syslog 4.0K Feb 4 02:56 . drwxr-xr-x 14 root root 4.0K Feb 4 02:46 .. drwxr-x--- 2 root adm 4.0K Feb 3 06:53 apache2 drwxr-xr-x 2 root root 4.0K Dec 27 21:46 apt drwxr-xr-x 2 root root 4.0K Feb 4 00:00 atop drwxr-xr-x 2 root root 4.0K Dec 27 21:46 dist-upgrade drwxr-xr-x 2 root root 4.0K Dec 27 21:46 fsck drwxr-xr-x 2 landscape root 4.0K Dec 27 21:46 landscape drwxr-s--- 2 mysql adm 4.0K Jan 25 17:45 mysql drwxrwxr-t 2 root postgres 4.0K Feb 3 06:53 postgresql drwxr-s--- 2 snort adm 4.0K Feb 3 06:25 snort drwxr-xr-x 2 root root 4.0K Feb 3 06:53 sysstat drwxr-xr-x 2 root root 4.0K Dec 27 21:46 unattended-upgrades drwxr-xr-x 2 root root 4.0K Feb 3 06:53 upstart |
This trick will only list files.
ubuntu ~/Documents $ ls -hula /home/ubuntu/Documents | grep ^- -rwxrwxr-x 1 ubuntu ubuntu 8.7K Oct 30 08:45 a.out -rw-rw-r-- 1 ubuntu ubuntu 101K Jan 27 22:06 documents.lst -rw-rw-r-- 1 ubuntu ubuntu 1.2K Nov 18 2015 hashes.out -rw-rw-r-- 1 ubuntu ubuntu 2.5K Jun 18 2015 hole.o -rw------- 1 ubuntu ubuntu 1.7K Jul 23 2017 id_rsa -rw-r--r-- 1 ubuntu ubuntu 404 Jul 23 2017 id_rsa.pub -rw-rw-r-- 1 ubuntu ubuntu 1.1K Jul 25 2017 my.c -rw-rw-r-- 1 ubuntu ubuntu 995 Oct 3 23:02 nikto-pinterest-log.log -rwxrwxr-x 1 ubuntu ubuntu 8.7K Oct 30 08:45 read -rw-rw-r-- 1 ubuntu ubuntu 1.3K Oct 30 08:45 read.c -rwxrwxr-x 1 ubuntu ubuntu 7.6K Mar 20 2015 recipe-502268-1.py -rw-rw-r-- 1 ubuntu ubuntu 256K Oct 15 2016 SAM -rw-rw-r-- 1 ubuntu ubuntu 64K Mar 23 2015 sam.save -rwxrwxr-x 1 ubuntu ubuntu 63K Nov 17 2015 secretsdump.py -rw-rw-r-- 1 ubuntu ubuntu 256K Nov 18 2015 SECURITY -rw-rw-r-- 1 ubuntu ubuntu 32K Mar 23 2015 security.save -rw-rw-r-- 1 ubuntu ubuntu 9.3M Oct 3 23:25 SYSTEM -rw-rw-r-- 1 ubuntu ubuntu 20M Mar 23 2015 system.save -rw-rw-r-- 1 ubuntu ubuntu 7.6K Oct 3 23:11 virii.S |
Use it like this to include the “.” and “..” entries in the directory listing.
Johns-MacBook-Air:~ jason$ ls -hula | grep ^dr drwxr-xr-x+ 18 jason staff 612B 4 Feb 22:12 . drwxr-xr-x 5 root admin 170B 4 Feb 22:11 .. drwx------ 2 jason staff 68B 4 Feb 22:03 .Trash drwx------ 43 jason staff 1.4K 17 Jan 21:40 .bash_sessions drwx------+ 7 jason staff 238B 4 Feb 22:11 Desktop drwx------+ 31 jason staff 1.0K 4 Feb 22:11 Documents drwx------+ 12 jason staff 408B 4 Feb 22:11 Downloads drwx------@ 54 jason staff 1.8K 4 Feb 22:11 Library drwx------+ 5 jason staff 170B 4 Feb 22:11 Movies drwx------+ 6 jason staff 204B 4 Feb 22:11 Music drwx------+ 3 jason staff 102B 4 Feb 22:11 Pictures drwxr-xr-x+ 5 jason staff 170B 4 Feb 22:11 Public |
To find out where you are in the directory structure, use the pwd command. It is very useful. Whether you are using Darwin or Linux.
Johns-MacBook-Air:~ jason$ pwd /Users/jason |
Another way to list all directories.
Johns-MacBook-Air:~ jason$ basename * Desktop Documents Downloads Library Movies Music Pictures Public |
