Hammer & Screwdriver Shell Script To E-Mail
Hi All,

I'm having some problems with my shell script. When running the script I get the following errors:

line 101: <html>: command not found
line 105: /dumpfile.txt: No such file or directory

The file dumpfile.txt does exist and I have double and tripple checked this. I'm not sure what I am doign wrong with the HTML tag part here as I want it to attach an html file. Any advice please?

Hi, you cannot use command substitution like this:
Code:
$(mysql_dump)

or
Code:
$(attachment)

This will try to execute the result of the substitution...

Ok, can you maybe help me get it working? I have manage to fix the first few errors and now I get the following:

Can't stat <html>: No such file or directory
<html>: unable to attach file.

Try using double quotes around variable references, for example "$(attachment)"

I tried this, and now it prints the output of the shell script. However it still doesn't attach and e-mail the file.

At the start of the print screen I get
Code:
Can't Stat

At the end I get
Code:
</html>: unable to attach file.

I have managed to get it to actually attach the file. But without and contents.

Hi, you need redirect on the first line:

Code:
cat <<-_Status_ > file

You would also need to call the function..

I still seem to be having a problem with the attachment actually containing any data. The script runs sending an e-mail with an HTML file attached, however when I open the HTML file it is blank. Below is what my script currently looks like.
