### Pulseway Service Check ###
### Log file location: /var/log/pulseway.log
### Add to crontab for hourly checks at half-past the hour, with no console output:
### 30 * * * * /root/pulseway-service-check.sh > /dev/null 2>&1
### This way, crontab doesn't try to email the result of the job

# Create $variable with the current service status

To enable SMART on a drive:
for sd in /dev/sd[a-f]; do echo $sd; smartctl --smart=on --offlineauto=on --saveauto=on $sd; done

For drives in USB enclosures, add the -d sat switch:
for sd in /dev/sd[a-z]; do echo $sd; smartctl --smart=on --offlineauto=on --saveauto=on -d sat $sd; done

To get the ERROR rate
for sd in /dev/sd[a-z]; do smartctl -A /dev/sdb | head -7| tail -1; smartctl -A /dev/sdb | grep Error_Rate | grep -v Multi

for sd in /dev/sd[a-e]; do echo $sd; smartctl -a $sd | grep Model ; smartctl -A $sd | head -7| tail -1; smartctl -A $sd | grep Error_Rate | grep -v Multi; done

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

Simply download files recursively. Note, that default maximum depth is set to 5.

$ wget --recursive https://example.org/open-directory/

Download files recursively using defined maximum recursion depth level. It is important to remember that level 0 is equivalent to inf infinite recursion.

$ wget --recursive --level 1 https://example.org/files/presentation/

Download files recursively and specify directory prefix. If not specified then by default files are stored in the current directory.
