Pre/Post Examples

Pre- and post-processing script examples.

Pre- and post-processing script examples are shown below ("bash" syntax). To run these examples on your own system, you must do the following:

Note:

Save example to /opt/aspera/var/myscript.sh
Ensure that the file is executable (e.g. chmod +x /opt/aspera/var/myscript.sh)
Add a line /opt/aspera/var/myscript.sh into /opt/aspera/var/aspera-prepost to call myscript.sh
Pay attention that you do not hit an exit condition in aspera-prepost before you call your script

Shell - Change file and directory permissions
In shell script, change file and directory permissions after receiving, and log into the file /tmp/p.log:
```
#!/bin/bash
if [ $TYPE == File ]; then
  if [ $STARTSTOP == Stop ]; then
    echo "The file is: $FILE" >> /tmp/p.log
    chmod 777 $FILE
  fi
fi
```

Shell - Forward files to another computer

In shell script, transfer received files to a third computer 10.10.10.10, and remove the local copy.

Important: For this example to work properly, the server's host key must be cached.

#!/bin/bash
TARGET=aspera@10.10.10.10:/tmp
RATE=10m
export ASPERA_SCP_PASS=aspera
if [ $TYPE == File ]; then
  if [ $STARTSTOP == Stop ]; then
    if [ $STATE == success ]; then
      if [ $DIRECTION == recv ]; then
        logger -plocal2.info "Move file $FILE to $TARGET"
        ascp -T -o RemoveAfterTransfer=yes -l $RATE $FILE $TARGET
      fi
    fi
  fi
fi

Shell - Create a log of successfully-transferred files

In shell script, store successfully-transferred file as a list into the file /tmp/aspera.transfer.log:

#!/bin/bash
if [ $TYPE == File ]; then
  if [ $STARTSTOP == Stop ]; then
    if [ $SIZE -gt 0 ]; then
      if [ `expr $SIZE - $STARTBYTE` -gt 0 ]; then
        echo `date` >> /tmp/aspera.transfer.log
        echo "$STATE $FILE $SIZE bits transferred" >> /tmp/aspera.transfer.log
      fi
    fi
  fi
fi
