I'm new in shell programming on macosx and have a little problem. I've written the following shell script:
#!/bin/sh
function createlink {
source_file=$1
target_file="~/$source_file"
if [[ -f $target_file ]]; then
rm $target_file
fi
ln $source_file $target_file
}
createlink ".netrc"
When I'm executing this script I get the message ln: ~/.netrc: No such file or directory and I don't know why this happened! Do you see the error? Thanks!

To solve No Such File Or Directory Error in Python, ensure that the file exists in your provided path. To check all the files in the directory, use the os. listdir() method.
log No such file or directory” the problem is most likely on the client side. In most cases, this simply indicates that the file or folder specified was a top-level item selected in the backup schedule and it did not exist at the time the backup ran.
First, make sure you execute the program with the correct path. If you make a typo on the directory or file name, you will get this error or give the wrong path. If you are executing the file with a relative path ( ../../file ), try executing with the absolute path ( /path/to/file ) instead.
The issue is that tilde expansion will not happen as the path is in a variable value (tilde expansion happens before variable expansion). You can ameliorate this issue by using $HOME instead of ~. That is
target_file="${HOME}/${source_file}"
This should solve your problem.
