Why not justsleep 3600; something.exe
? Does that not work in Windows?
On Unix, I generally use ( sleep 60m; xterm -bg red ) & to set a timer to pop up a big red window after an hour, without tying up the shell.
Some of my favorites:
Scan a log file generated by strace -tt, looking for each second turnover: (should
statistically find the operations requiring the most time)
perl -lane 'print $last if ($F ne $lastt); $last = $_; $lastt = $F[
Print out a running sum of the 3rd column of a file:
perl -lane 'print $s += $F'
Rewrite all of the CVS/Root files in a tree (yes, this is a weird way to do it):
find . -name 'Root' -print0 | xargs -0 perl -i -pe '$_=q(:pserver:sfin
Print out all the double-quoted strings in a file:
perl -lne 'print $1 while (/\"(.*?)\"/g)' filename
Somewhat more robust version (handles backslashes):
perl -lne 'print $1 while (/\"((\\.|[^\"])*)\"/g)' filename
Print out all of the C++ constructors in a set of files:
perl -lne 'print if /(\w+)::\1/ .. /^\}/' *.cpp
I don't know if those are really representative of my favorites. I normally just spew them out on demand, so it's difficult to think of them when I don't actually need them. The above are just the ones I've used recently enough to remember.
