Top Forums Shell Programming and Scripting Add leading zeroes to numbers in a file Post 302206262 by raidzero on Tuesday 17th of June 2008 10:42:40 AM

wish I would have looked around a little more before posting. This is what helped me out:

Code:
awk '{for (i=1; i<NF; i++) $i=sprintf("%02d", $i); print; }' /tmp/uidle

At this point though, I need to reorder the numbers inside the file in descending order. I know how to do it in ascending order with
Code:
cat /tmp/uidle | sort -k1

How do I reverse it? Or just sort the opposite way to begin with?

KILL(1) 							Linux User's Manual							   KILL(1)

NAME
kill - send a signal to a process SYNOPSIS
kill [ -signal | -s signal ] pid ... kill [ -L | -V, --version ] kill -l [ signal ] DESCRIPTION
The default signal for kill is TERM. Use -l or -L to list available signals. Particularly useful signals include HUP, INT, KILL, STOP, CONT, and 0. Alternate signals may be specified in three ways: -9 -SIGKILL -KILL. Negative PID values may be used to choose whole process groups; see the PGID column in ps command output. A PID of -1 is special; it indicates all processes except the kill process itself and init. SIGNALS
The signals listed below may be available for use with kill. When known constant, numbers and default behavior are shown. Name Num Action Description 0 0 n/a exit code indicates if a signal may be sent ALRM 14 exit HUP 1 exit INT 2 exit KILL 9 exit cannot be blocked PIPE 13 exit POLL exit PROF exit TERM 15 exit USR1 exit USR2 exit VTALRM exit STKFLT exit might not be implemented PWR ignore might exit on some systems WINCH ignore CHLD ignore URG ignore TSTP stop might interact with the shell TTIN stop might interact with the shell TTOU stop might interact with the shell STOP stop cannot be blocked CONT restart continue if stopped, otherwise ignore ABRT 6 core FPE 8 core ILL 4 core QUIT 3 core SEGV 11 core TRAP 5 core SYS core might not be implemented EMT core might not be implemented BUS core core dump might fail XCPU core core dump might fail XFSZ core core dump might fail NOTES
Your shell (command line interpreter) may have a built-in kill command. You may need to run the command described here as /bin/kill to solve the conflict. EXAMPLES
kill -9 -1 Kill all processes you can kill. kill -l 11 Translate number 11 into a signal name. kill -L List the available signal choices in a nice table. kill 123 543 2341 3453 Send the default signal, SIGTERM, to all those processes. SEE ALSO
pkill(1), skill(1), kill(2), renice(1), nice(1), signal(7), killall(1). STANDARDS
This command meets appropriate standards. The -L flag is Linux-specific. AUTHOR
Albert Cahalan <albert@users.sf.net> wrote kill in 1999 to replace a bsdutils one that was not standards compliant. The util-linux one might also work correctly. Please send bug reports to <procps-feedback@lists.sf.net> Linux November 21, 1999 KILL(1)
