Re: How to generate a temp file until finish selected then replace to another file.

Ot create a file and pipe something into it whatever you like you can use the redirect to a file

Shell Scripting Syntax (Toggle Plain Text)

echo "hello" > /tmp/temp.txt

This will open a new file or overwrite an existing file in the same location and then put the text hello into /tmp/temp.txt. If you want to add addtional lines use the following command

Shell Scripting Syntax (Toggle Plain Text)

echo "hello chris" >> /tmp/temp.txt

You file will then contain hello followed by hello chris to move this file from one location to the other use the following code

Shell Scripting Syntax (Toggle Plain Text)

mv location1 location2
e.g
mv /tmp/temp.txt /tmp/finished.txt

Re: How to generate a temp file until finish selected then replace to another file.

Do you use the temporary file for anything in the meantime? I'm biased against temporary files when they can be avoided, personally... Why not stuff it all into a variable and then stuff it into a file when it's done, or just write directly to the destination file? Here's an example of using a variable:

Shell Scripting Syntax (Toggle Plain Text)
## the quotes are important!
RESULT="$(command --switches)"
echo "$RESULT" > /tmp/finished.txt
## the quotes are important!
RESULT="$(command --switches)"
echo "$RESULT" > /tmp/finished.txt

Hope that helps!
