brew install t-recsudo port selfupdate
sudo port install t-recNOTE t-rec depends on imagemagick.
brew install imagemagick
cargo install -f t-rec NOTE -f just makes sure the latest version is installed
sudo apt-get install imagemagick
wget https://github.com/sassman/t-rec-rs/releases/download/v0.5.0/t-rec_0.5.0_amd64.deb
sudo dpkg -i t-rec_0.5.0_amd64.deb
- installation for Linux Mint
- installation for Arch Linux
TL;DR:
sudo snap install t-rec --classic
/snap/bin/t-rec --version
t-rec 0.4.3t-rec can be installed from available AUR packages using an AUR helper. For example,
paru -S t-rec
If you prefer, you can clone the AUR packages and then compile them with makepkg. For example,
git clone https://aur.archlinux.org/t-rec.git
cd t-rec
makepkg -si
pkgin install t-rec
Or, if you prefer to build from source,
cd /usr/pkgsrc/multimedia/t-rec
make install
sudo apt-get install libx11-dev imagemagick
cargo install -f t-rec| tested on those distros |

t-recor with specifying a different program to launch
t-rec /bin/sht-rec 0.7.6

Blazingly fast terminal recorder that generates animated gif images for the web written in rust.
Usage: t-rec [OPTIONS] [shell or program to launch]
Arguments:
[shell or program to launch] If you want to start a different program than $SHELL you can
pass it here. For example '/bin/sh'
Options:
-v, --verbose Enable verbose insights for the curious
-q, --quiet Quiet mode, suppresses the banner:
'Press Ctrl+D to end recording'
-m, --video Generates additionally to the gif a mp4 video of the recording
-M, --video-only Generates only a mp4 video and not gif
-d, --decor <decor> Decorates the animation with certain, mostly border effects
[default: none] [possible values: shadow, none]
-b, --bg <bg> Background color when decors are used [default: transparent]
[possible values: white, black, transparent]
-n, --natural If you want a very natural typing experience and disable the idle
detection and sampling optimization
-l, --ls-win If you want to see a list of windows available for recording by
their id, you can set env var 'WINDOWID' or `--win-id` to record
this specific window only
-w, --win-id <win-id> Window Id (see --ls-win) that should be captured, instead of
the current terminal
-e, --end-pause <s | ms | m> to specify the pause time at the end of the animation, that time
the gif will show the last frame
-s, --start-pause <s | ms | m> to specify the pause time at the start of the animation, that time
the gif will show the first frame
-o, --output <file> to specify the output file (without extension) [default: t-rec]
-h, --help Print help
-V, --version Print version
If you are not happy with the idle detection and optimization, you can disable it with the -n or --natural parameter.
By doing so, you would get the very natural timeline of typing and recording as you do it.
In this case there will be no optimizations performed.
In order to enable the drop shadow border decor you have to pass -d shadow as an argument. If you only want to change
the color of the background you can use -b black for example to have a black background.
You can record not only the terminal but also every other window. There 3 ways to do so:
- use
-w | --win-idargument to name the Window Id that should be recorded
t-rec --ls-win | grep -i calc
Calculator | 45007
t-rec -w 45007 - use the env var
TERM_PROGRAMlike this:
- for example lets record a window 'Google Chrome'
- make sure chrome is running and visible on screen
TERM_PROGRAM="google chrome" t-rec
Frame cache dir: "/var/folders/m8/084p1v0x4770rpwpkrgl5b6h0000gn/T/trec-74728.rUxBx3ohGiQ2"
Recording window: "Google Chrome 2"
Press Ctrl+D to end recording
this is how it looks then:
- use the env var
WINDOWIDlike this:
- for example let's record a
VSCodewindow - figure out the window id program, and make it
- make sure the window is visible on screen
- set the variable and run
t-rec
t-rec --ls-win | grep -i code
Code | 27600
# set the WINDOWID variable and run t-rec
WINDOWID=27600 t-rec
Frame cache dir: "/var/folders/m8/084p1v0x4770rpwpkrgl5b6h0000gn/T/trec-77862.BMYiHNRWqv9Y"
Press Ctrl+D to end recording
this is how it looks then:
