Accepted Answer

You could pipe error info from your script to a file and grep for an error with a second script. The second script could even run the first and might look something like this:

```
/path/firstscript.sh 2>&1 > results.txt
if [ -n "$(grep 'error expected' results.txt)" ]
 then 
  echo "Found error" | mail -S "Error" you@example.com
 else
  echo "No error" | mail -s "Okay" you@example.com
 fi
```

Personally, I find it better to check for the file on the target site by doing a second connection and listing the output there. Then I check that second connection log for the existence of the uploaded file.

I can't use rsync or key authentication with three different companies I script file transfers for, so I have some sympathy for people who get the answer "don't do that" when they ask a question. It's worse when you're searching for the answer because you already know that what people are recommending instead won't work.

Here's examples more closely based on what I actually do:

email_result.bash

```
#!/bin/bash
./uploadfile_example.bash 2>&1 > log.txt
if [ -n "$(grep "$(date +%b' '%d)" log.txt|grep "testfile")" ]
 then
  echo "File uploaded" |mail -s "Test success" you@example.com
 else
  echo "File not uploaded" |mail -s "Test fail" you@example.com
 fi
```

uploadfile_example.bash

```
#!/bin/bash
datestamp=$(date +%s)
/bin/cp -v testfile.txt testfile.${datestamp}.txt
HOST="localhost"
USER="testuser"
PASS="YourPasswordHere"

expect -c "
spawn sftp ${USER}@${HOST}
expect \"password: \"
send \"${PASS}\r\"
expect \"sftp>\"
send \"put testfile.${datestamp}.txt\r\"
expect \"sftp>\"
send \"ls -l testfile.${datestamp}.txt\r\"
expect \"sftp>\"
send \"bye\r\"
expect \"#\"
"

/bin/rm -vf testfile.${datestamp}.txt
```
