It's common to want to split up large files and the usual method is to use split(1).
If you have a 10GiB file, you'll need 10GiB of free space.
Then the OS has to read 10GiB and write 10GiB (usually on the same filesystem).
This takes AGES.
.
The command uses a set of loop block devices to create fake chunks, but without making any changes to the file.
This means the file splitting is nearly instantaneous.
The example creates a 1GiB file, then splits it into 16 x 64MiB chunks (/dev/loop0 .. loop15).
.
Note: This isn't a drop-in replacement for using split. The results are block devices.
tar and zip won't do what you expect when given block devices.
.
These commands will work:
$ hexdump /dev/loop4
.
$ gzip -9 < /dev/loop6 > part6.gz
.
$ cat /dev/loop10 > /media/usb/part10.bin
Pump up the chatter, run this script on a regular basis to listen to your twitter timeline.
This is a rough first cut using several cli clips I have spotted around. There is no facility to not read those things already read to you. This could also easily be put in a loop for timed onslaught from the chatterverse, though I think it might violate several pointsof the Geneva Convention
UPDATE - added a loop, only reads the first 6 twits, and does this every 5 mins.
Nasty perl one-liner that provides a sparkline of ping times. If you want a different history than the last 30, just put that value in. It (ab)uses unicode to draw the bars, inspired by https://github.com/joemiller/spark-ping . It's not the most bug-free piece of code, but what it lacks in robustness it makes up for in capability. :)
If anyone has any ideas on how to make it more compact or better, I'd love to hear them.
I included a ping to google in the command just as an example (and burned up 10 chars doing it!). You should use it with: $ ping example.com | $SPARKLINE_PING_COMMAND
If you spot a dubious looking cp command running you can use this command to view what is being copied and to where.
1234 is the PID of the cp command being passed to the lsof utility.
3r.*REG will display the file/directory that is being read/copied.
4w.*REG will display the destination it is being written to.
This also works with Safari if you just change the application name. Replace
$ window 1
with
$ windows
to list the URLs of tabs in all windows instead of only the frontmost window. This also includes titles:
$ osascript -e{'set o to""','tell app"google chrome"','repeat with t in tabs of window 1','set o to o&url of t&"\n"&" "&title of t&"\n"',end,end}|sed \$d
.
less symbols, tab completion.
including # export SIMPLE_BACKUP_SUFFIX="_`date +%F`" in your .bashrc provides you to easily timestamp your files
