Misc Linux tips and tricks

R Studio Data Recovery doesn't start with:
/usr/local/R-Studio/bin/R-Studio: error while loading shared libraries: librs_linux_r.so: cannot open shared object file: No such file or directory

$ sudo vi /etc/ld.so.conf.d/rstudio.conf

Change words in multiple docs:

$ grep -rl 'Tcphost' ./ | sudo xargs sed -i 's/Tcphost/TCP Host/g'
$ grep -rl 'Tcpport' ./ | sudo xargs sed -i 's/Tcpport/TCP Port/g'

Mount a VDI disk image:

$ sudo modprobe nbd max_part=16
$ sudo qemu-nbd -c /dev/nbd0 ./home-logger.vdi
$ ls -lh /dev/nbd0*
<this lists all the partitions in the vdi>

Choose which of the partitions you want to mount (eg 1st partition), then:

$ sudo mount /dev/nbd0p1 /mnt

When done, unmount it:

$ sudo qemu-nbd -d /dev/nbd0

Remove forbidden characters from files (for Samba share):

SERVER> find . | perl -l -ne '/^([\000-\177]|[\300-\337][\200-\277]|[\340-\357][\200-\277]{2}|[\360-\367][\200-\277]{3}|[\370-\373][\200-\27
7]{4}|[\374-\375][\200-\277]{5})*$/ or print'
