Cheers everyone 🙂
I’m trying to make a linux script. This script shall be called with one parameter, a file stored in my home directory. I can’t seem to use
cat $var1 >> $1
So i have this variable $var1 and I want to save it in a file that does exist and its name is given in $1
Anyone help me please!

The cat command shows the contents of a file.
Unless the value of $var1 is a file that you want to ‘copy’ to $1, it won’t work (probably gives a ‘file not found’ kind of error).
The easiest solution, I can think of, is to echo the variable:
echo "$var1" >> "$1"
As stated by @glglgl it is better to put the variable between double quotes. They prevent spaces messing up the command as they split a parameter into multiple parameters
