$ ls -la /proc/$$/fdtotal 0dr-x------ 2 sorontar sorontar 0 Dec 28 00:56 .dr-xr-xr-x 9 sorontar sorontar 0 Dec 28 00:56 ..lrwx------ 1 sorontar sorontar 64 Dec 28 00:56 0 -> /dev/pts/6lrwx------ 1 sorontar sorontar 64 Dec 28 00:56 1 -> /dev/pts/6lrwx------ 1 sorontar sorontar 64 Dec 28 00:56 2 -> /dev/pts/6lrwx------ 1 sorontar sorontar 64 Dec 28 00:56 255 -> /dev/pts/6l-wx------ 1 sorontar sorontar 64 Dec 28 00:56 4 -> /home/sorontar/testfile.txt
