I am writing a script that among other things will be checking for various files on mount points. One of the conditions is that unless the server has failed over the df command will show root ( / ). If when checking the files the script comes across /, I want it to skip it, otherwise to complete the printf statement.
This portion of the script is
Please put code inside [code] tags (and forget all that silly FONT and SIZE crap).

However, since that really isn't code ...

When running, if the script comes across a / I am receiving a 'Division by 0' error and it will abort the query.
Why would you be using any of the mount points as a divisor?
how can i show the value when i divide a number where the dividend is greater then the divisor. for example...
3 divided by 15 ---> let x=3/15
when i do this in the shell environment it gives me an output of 0.
please help me.
thanks. (3 Replies)
Hi All,
I'm reasonably new to UNIX, and am having problems with a TSHELL script that I am using. The script is intended to cycle through a loop, and then divide the number in the counter by 10 and store the result in another variable. I am missing something simple here, but cannot work it out... (1 Reply)
How can I modify my awk code to get rid of the divion by zero error message? If I run the script without an input file, it should return error message "Input file missing" but not divison by zero.
Code:
#!/bin/nawk -f
BEGIN {
if (NR == 0)

Hello,

hi,
The below commands result only the whole number(not giving the decimal values).
pandeeswaran@ubuntu:~$ echo 1,2,3,4|sed 's/,/\//g'|bc
0
pandeeswaran@ubuntu:~$ echo 1000,2,3|sed 's/,/\//g'|bc
166
How to make it to return the decimal values?
Thanks (5 Replies)
Hello,
How can I add a logic to awk to tell it to print 0 when encountering a division by zero attempted? Below is the code. Everything in the code works fine except the piece that I want to calculate read/write IO size. I take the kbr / rs and kbw / ws. There are times when the iostat data... (5 Replies)
I want to implement the below formula with awk oneliner
new_value = ((old_value - old_min) / (old_max - old_min) ) * (new_max - new_min) + new_min
I want to pass the value of old_min and old_min as variable. Here is what I did for this
old_min=$(awk 'BEGIN{a=100000000000}{if ($10<0+a) a=$10}... (2 Replies)

switch_root
SWITCH_ROOT(8) System Administration SWITCH_ROOT(8)NAME
switch_root - switch to another filesystem as the root of the mount tree
SYNOPSIS
switch_root [-hV]
switch_root newroot init [arg...]
DESCRIPTION
switch_root moves already mounted /proc, /dev and /sys to newroot and makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on the current root filesystem.
OPTIONS -h, --help
show help and exit
-V, --version
show version number and exit
RETURN VALUE
switch_root returns 0 on success and 1 on failure.
NOTES
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:
mount --bind $DIR $DIR
