• TecMint ☛ How to Host A Website for Free at Your Home Linux System

• TecMint ☛ 4 Tools to Find Which Linux Process Is Using Your Bandwidth

  You check top or htop, but everything looks fine because those tools only show CPU and memory, not network usage. So you know something is eating bandwidth, but you cannot actually see what it is.

• Vermaden ☛ Expand GELI Encrypted Bhyve VM ZFS Disk

  Today we will follow them one by one to expand GELI encrypted ZFS disk.

  There is only one potential problem – and I faced that recently with one of the other VMs I manage.

  If FreeBSD VM guest version is older – I have tested with 14.1-RELEASE for example – then even these will not help: [...]

• [Old] Dan Langille ☛ Creating an Apple Time Capsule using FreeBSD & ZFS

  First, all credit goes to Mark Felder’s blog post upon which this is based.

  You can buy an Apple Time Capsule (I did) to back up your Mac. Now that I have two MacBook’s, I have run out of space, so now I want to backup to ZFS.

  By backing up to my ZFS filesystem: [...]

  • Linux Capable ☛ bzip2recover Command in Linux: Recover Damaged BZ2 Files

    When a .bz2 file will not decompress, this workflow keeps the damaged source intact, splits recoverable blocks, tests each piece, and rebuilds usable text or tar data without pretending the archive is fully repaired.

  • Linux Capable ☛ bzip2 Command in Linux: Compress, Decompress, and Test .bz2 Files

    Practice bzip2 on disposable files before touching real backups, including keep-original compression, stdout pipelines, tar.bz2 archives, integrity tests, wrong-format checks, and recovery limits.

  • Linux Capable ☛ bunzip2 Command in Linux: Decompress .bz2 Files

    Restore bzip2-compressed files without losing the source copy by choosing the right bunzip2 pattern for .bz2 streams, tar.bz2 archives, stdin pipelines, batch restores, and common errors.

  • Linux Capable ☛ bzcat Command in Linux: Read .bz2 Files Without Extracting

    Inspect compressed logs, SQL dumps, and text exports with bzcat without unpacking them first. The examples cover safe streams, redirection, grep/tail pipelines, integrity checks, and common bzip2 errors.

  • Linux Capable ☛ bzgrep Command in Linux: Search .bz2 Files

    Search compressed logs without unpacking them, learn when bzgrep should hand off to find or tar, and handle wrapper quirks such as missing aliases, -H labels, recursive searches, and bad .bz2 data.

  • Linux Capable ☛ bzless Command in Linux: View .bz2 Files Without Extracting

    Compressed log reviews are safer when bzless stays in the pager lane: open .bz2 text, search inside the file, use bzcat for clean pipelines, and test suspect streams before trusting them.

  • Linux Capable ☛ bzmore Command in Linux: View .bz2 Files One Screen at a Time

    Page through bzip2-compressed logs and text exports with bzmore, then switch to bzgrep, bzcat, bzip2 -t, or tar when searching, scripting, validating, or inspecting archives.

  • Linux Capable ☛ dos2unix Command in Linux: Convert CRLF Line Endings

    Fix backdoored Windows line endings without guessing: inspect CRLF files first, convert single or bulk text files safely, preserve timestamps when needed, and troubleshoot script or binary-skip surprises.

  • Linux Capable ☛ Bash Aliases in Linux: Create, Save, and Troubleshoot

    Repeated terminal commands become easier to manage when Bash aliases stay small, visible, and stored in the right startup file, with functions reserved for arguments and checks for aliases that shadow real commands.
