==catfish== (xfce)

sudo apt install catfish
catfish -help

# not case sensitive
# some examples searches for 'geometry' inside all files in path /mnt/data/SYS/scripts
catfish --fulltext /mnt/data/SYS/scripts  geometry  & disown 
catfish --fulltext /mnt/data/creata/scripta/ Dugin  & disown 
catfish --fulltext /mnt/data/ 'Keith Woods'  & disown 

( catfish is also used together with xfce Thunar , , you need to configure Thunar for that ? )

==recoll==   [in synaptic]

desktop search on content (like microsoft search or FT ) ik gebruik het op windows machines
https://en.wikipedia.org/wiki/Recoll
/mnt/data/SYS/scripts/scripts.bash/1 find-locate/recoll-fulltext-search.txt
/usr/share/app-install/desktop/recoll:recoll-searchgui.desktop
=> not installed / uninstalled ? ( space man werkt goed genoeg ? )

Spaceman FM Search

SpacemanFM has a file content search functionality included, with a nice GUI
? is this a life search , not indexed ; a wrapper arround grep command ?
== > grep proces launches with big cpu & big IO

other

• gnome-search-tool
  removed from ubuntu/mint repo for being unmaintained
• search monkey
  if you’re searching the entire filesystem, searchmonkey gets lost in /proc and takes forever.
  use find command with -xdev option to search only real files in the current filesystem
• ~~DocFetcher~~
  DocFetcher free is old code base, no more new features , DocFetcher Pro is (2020) completely rewritten , paid version
• Traker
  https://wiki.gnome.org/Projects/Tracker/
• default win + S open a search bar above clock applets
  doesn’t yield results , indexing is turned of ?
  what tool does it use ? =>
