ffmpeg -nostats -i pohokolius_-_odlazak_remastered.flac -af astats=metadata=0 -f null - 2>&1 | grep "Bit depth"

Wed, 26 Aug 2026 21:00:00 GMT

This commands exposes effective depth of an audio file. Example: if it comes back as something like 16/24/24/24, the source was 16-bit content in a 24-bit wrapper.

grep -E '^he_' /var/run/hostapd-phy*.conf | grep -v mu_edca

Sun, 26 Jul 2026 21:00:00 GMT

Dumps the active 802.11ax operating parameters minus the MU-EDCA defaults. Shows he_oper_chwidth (0=20/40, 1=80, 2=160), spatial reuse control, BSS color, TWT requirement and beamforming roles in one view.

iw phy1 info | grep -A 10 'valid interface combinations'

Sun, 26 Jul 2026 21:00:00 GMT

Reports the maximum number of AP interfaces the radio hardware supports.

iw dev phy1-ap0 station dump | grep -c Station

Sun, 26 Jul 2026 21:00:00 GMT

Counts currently associated wireless clients on an interface. Useful for checking whether a txpower reduction dropped edge clients, when run repeatedly over time.

iw dev phy1-ap0 station dump | grep -E 'Station|signal:|tx bitrate|rx bitrate'

Sun, 26 Jul 2026 21:00:00 GMT

Shows per-client uplink signal and negotiated rates. Only measures what the AP receives, so it cannot be used to evaluate AP transmit power changes. Clients must be passing traffic or rates read low.

iw dev phy1-ap0 survey dump | grep -A7 'in use'

Sun, 26 Jul 2026 21:00:00 GMT

Reports noise floor plus channel active/busy time for the operating channel. Divide busy by active for airtime utilization; under ~20 percent is healthy, over ~50 percent means real contention.

iwinfo phy1-ap0 info | grep -E 'Channel|Tx-Power'

Sun, 26 Jul 2026 21:00:00 GMT

Shows the channel, center channel, HT mode and post-regdb-clamp Tx-Power actually in effect on a wireless interface.

Thu, 23 Apr 2026 21:00:00 GMT

Resizes an image to fill a 1200x630 canvas, centering the content and cropping any overflow.

find . -maxdepth 1 -mindepth 1 -type d -exec rm -rf '{}' \;

Wed, 08 Apr 2026 21:00:00 GMT

Deletes all directories within the current folder while preserving the files in the root. Uses -maxdepth 1 to prevent recursion into sub-subdirectories.

python3 -c "import re,sys,pathlib;p=re.compile(r'[\U0001f300-\U0001f9ff\U00002702-\U000027b0\U0000fe00-\U0000fe0f\U0000200b-\U0000200f\U0000200d]');[print(f'{f}:{i+1}: {l.rstrip()[:80]}') for f in pathlib.Path(sys.argv[1]).rglob('*') if f.suffix in ('.html','.md','.txt') for i,l in enumerate(f.read_text('utf-8').splitlines()) if p.search(l)]" ./

Fri, 20 Mar 2026 22:00:00 GMT

Scans all .html, .md, and .txt files recursively for emoji and zero-width characters (ZWJ, variation selectors, invisible formatters). Prints filename:line:preview for each hit. Safe for multilingual content (Cyrillic, CJK etc.), only targets Unicode emoji and control ranges.

pkg info -r ImageMagick7

Wed, 11 Mar 2026 22:00:00 GMT

Lists all installed packages that depend on a given package.

gzip --best -k file.svg && mv file.svg.gz file.svgz

Wed, 11 Mar 2026 22:00:00 GMT

Compresses an SVG file into the SVGZ format. The -k flag preserves the original.

dnf repoquery --installed --whatrequires ImageMagick7

Wed, 11 Mar 2026 22:00:00 GMT

Lists all installed packages that depend on a given package. Answers: 'what would break if I removed this?'

magick main_screen.png -background none -size 20x1 xc:none results.png +append kalkulator-prostih-brojeva-app-pregled.png

Wed, 11 Mar 2026 22:00:00 GMT

Horizontally appends images with a transparent spacer between them. Creates a 20x1 transparent canvas as a gap, then uses +append to stitch all images side by side into a single output file.

awk -F'[<>]' '// {print $3}' sitemap.xml

Thu, 12 Feb 2026 22:00:00 GMT

Extracts raw URLs from a standard XML sitemap with awk. Matches and captures text strictly between tags.

sed -n 's/.$.$<\/loc>.*/\1/p' sitemap.xml

Thu, 12 Feb 2026 22:00:00 GMT

Extracts raw URLs from a standard XML sitemap. Matches and captures text strictly between tags, replacing the entire line with the URL. Works on FreeBSD/BSD sed.

top -o res

Mon, 09 Feb 2026 22:00:00 GMT

Sorts FreeBSD process list by resident set size (RSS, physical RAM). Essential for ignoring misleading virtual memory ('SIZE') stats, which often show terabytes of reserved address space for electron/Go apps. 'RES' reveals the actual physical memory cost.

magick gshock-gw-m5610u-1b.png -fill "#fbfbfe" -opaque "#e6f1f5" -fill "#1c1b22" -opaque "#203a43" gshock-gw-m5610u-1b_darkgrey.png

Wed, 04 Feb 2026 22:00:00 GMT

Swaps specific hex colors 1:1 on the image. Replaces Light (#e6f1f5) with off-white (#fbfbfe) and dark (#203a43) with dark-grey (#1c1b22). Uses sequential fill/opaque operations.

printf 'dev.hwpstate_intel.0.epp=100\ndev.hwpstate_intel.1.epp=100\ndev.hwpstate_intel.2.epp=100\ndev.hwpstate_intel.3.epp=100\n' | sudo tee -a /etc/sysctl.conf && sudo sysrc powerd_enable='NO'

Tue, 03 Feb 2026 22:00:00 GMT

Appends Intel HWP powersave settings to sysctl.conf (making them permanent) and disables the obsolete 'powerd' service in rc.conf. Useful for libreboot systems.

sysctl dev.cpu.0.freq_levels

Tue, 03 Feb 2026 22:00:00 GMT

Checks available CPU frequency steps. If output is single-level (e.g., '2700/-1') on Libreboot/modern Intel, ACPI tables are missing. Discard 'powerd' and rely on 'hwpstate_intel' (Hardware P-States) for frequency scaling.
