I wrote a very simple program to test outputting data to a file name variable.
#!/bin/sh
file="~/output"
echo "test" > $file
When I run this script, I got the following error
"./script.sh: line 3: ~/output: No such file or directory"
So how should I revise my code to get it work? Or it's not supported in shell script?
The quotes around the "~/output" are causing you grief.
e.g
#!/bin/sh
file=~/output
echo "test" > $file
works ok.
To see what's going on, try
$ file="~/output"
$ echo $file
vs
$ file=~/output
$ echo $file
and bear in mind that ~ is a shell expansion for the home directory.
You can use the $HOME environment variable instead in a script:
#!/bin/sh
file="$HOME/output"
echo "test" > $file
