go read the user guide fr fr, it's giving tutorial energy and you will need it 📚

---

✨ OPTIONS ✨

• --style[=STYLE] — this one forces the QT5 style to STYLE. and what can STYLE be, you ask? Fusion (which is the default, she's the main character) or Windows. that's it, that's the list 💅
• -r, --rig-name[=RIGNAME] — bestie this is the multitasking queen 👑 it lets you run multiple instances of the jtdx(1) application at the same time. each RIGNAME has to be unique tho, no cap. one instance is allowed to use no RIGNAME at all. but heads up — if you don't supply this option, then only one instance of jtdx(1) can run at any time. periodt.
• -v, --version — shows you the application version. quick lil vibe check on what you're running 🌈
• -h,--help — displays usage information. the classic, the legend, the "help me bestie" button 🫶
• --test-mode — when you provide this option, all writable files get placed in a special test location: ~/.qttest. ok so real talk, this option is only for application testing and is not designed for normal operations. use with caution ⚠️ like, do not make this your whole personality, she's for experiments only 🙈

🍓 FILES 🍓

most of the files below live in a directory path that contains the directory name JTDX[ - RIGNAME] — and that bracket thing is showing you the value of the command line option --rig-name=RIGNAME, which is how you get multiple instances of jtdx running concurrently. so basically, all the writable files listed below are unique to each concurrent instance of jtdx. if you don't supply the --rig-name command line option, or you don't supply the RIGNAME argument, then the directory paths below just have the directory JTDX. simple as 💅

• ~/.config/JTDX[ - RIGNAME].ini — this file stores the application configuration settings. the whole personality lives here ✨
• ~/.local/share/JTDX[ - RIGNAME]/yyyymm_ALL.txt — ALL.txt contains a record of transmitted and received messages, plus other activity like frequency or band changes. it's the receipts folder fr fr 📝
• ~/.local/share/JTDX[ - RIGNAME]/save/ — this is the default location for saved .WAV files recorded by the application. lowkey you can change the .WAV file save location in the applications settings dialog if you want 🎧
• ~/.local/share/JTDX[ - RIGNAME]/save/samples/ — sample .WAV files supplied with the application are found in this directory. you can play them back in the application, and they get referred to in the user guide tutorial sections. cute lil study materials 🧚
• ~/.local/share/JTDX[ - RIGNAME]/cty.dat — okay so this file is not required, because a version of it is embedded in the application. but if you want, an updated version can be placed here — and if it's present, that version will be used in preference to the embedded version. glow up your country data, why not 🌍
• ~/.local/share/JTDX[ - RIGNAME]/wsjtx.log — a plain text CSV record of logged QSOs. old school, still slaying 💾
• ~/.local/share/JTDX[ - RIGNAME]/wsjtx_log.adi — a record of QSOs logged in the ADIF format, which is suitable for import into many Ham Radio logging programs. she plays well with others 🫶
