Problem
Is something along these lines:
cat "Some text here." > myfile.txt
Possible? As a result, the contents of myfile.txt have been overwritten to:
Some text here.
This doesn’t work for me, but it doesn’t give me any errors either.
I’m looking for a cat-based solution (not vim/vim/emacs, etc.). Cat is shown in all online examples in connection with file inputs, not raw text…

That is exactly what echo does:
echo "Some text here." > myfile.txt

For text file:
cat > output.txt <<EOF
some text
some lines
EOF
For PHP file:
cat > test.php <<PHP
<?php
echo "Test";
echo \$var;
?>
PHP

To change my CPU settings, I use the following code to write raw text to files. I hope this information is useful. Script:
#!/bin/sh
cat > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor <<EOF
performance
EOF
cat > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor <<EOF
performance
EOF
The text “performance” is written to the two files stated earlier in the script. This sample overwrites files with old data.
To make this code executable, save it into a file (cpu update.sh) and run it:
chmod +x cpu_update.sh
After that, you can use the following command to start the script:
./cpu_update.sh
If you don’t want to overwrite the file’s old data, replace it.
cat > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor <<EOF
with
cat >> /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor <<EOF
This will append your text to the end of the file without overwriting any existing information.
