  • The Linux /dev/full file simulates a "disk full" condition, and can be used to verify how a program handles this situation. In particular, several programming language implementations do not print error diagnostics (nor exit with error status) when I/O errors like this occur, unless the programmer has taken additional steps. That is, simple code in these languages does not fail safely. In addition to Perl, C, C++, Tcl, and Lua (for some functions) also appear not to fail safely. Show Sample Output

    perl -e 'print 1, 2, 3' > /dev/full

  • I use this (well I normally just drop the F=*.log bit and put that straight into the awk command) to count how many times I get referred from another site. I know its rough, its to give me an idea where any posts I make are ending up. The reason I do the Q="query" bit is because I often want to check another domain quickly and its quick to use CTRL+A to jump to the start and then CTRL+F to move forward the 3 steps to change the grep query. (I find this easier than moving backwards because if you group a lot of domains with the pipe your command line can get quite messy so its normally easier to have it all at the front so you just have to edit it & hit enter). For people new to the shell it does the following. The Q and F equals bits just make names we can refer to. The awk -F\" '{print $4}' $F reads the file specified by $F and splits it up using double-quotes. It prints out the fourth column for egrep to work on. The 4th column in the log is the referer domain. egrep then matches our query against this list from awk. Finally wc -l gives us the total number of lines (i.e. matches). Show Sample Output
