A primitive script. This will check if total disk space used is >= 90% once in every 10s and if so, an email will be sent. It'll run in an infinite loop until you kill it.

Hello,
Can someone please tell me which command to use to determine the available disk space on a given disk device?
I have to write a shell script that compresses files and stores them in a specific location but I am not sure how "conservative" I should be?
Thanks in advance!

I'm a Unix newbie running Solaris 9. After installing a fresh copy on a 40GB drive I noticed the available disk space is 2% free or approximately 200MB available. Is that possible? Did I do something wrong? (4 Replies)
Hi,
I am using SCO Unix 3.12 and Informix database. When we tried to use "du -a" command to check disk space, it showed:

AT(1) General Commands Manual AT(1)NAME
at - execute commands at a later time
SYNOPSIS
at [ -c ] [ -s ] [ -m ] time [ day ] [ file ]
DESCRIPTION
At spools away a copy of the named file to be used as input to sh(1) or csh(1). If the -c flag (for (csh(1))) or the -s flag (for (sh(1)))
is specified, then that shell will be used to execute the job; if no shell is specified, the current environment shell is used. If no file
name is specified, at prompts for commands from standard input until a ^D is typed.
If the -m flag is specified, mail will be sent to the user after the job has been run. If errors occur during execution of the job, then a
copy of the error diagnostics will be sent to the user. If no errors occur, then a short message is sent informing the user that no errors
occurred.
The format of the spool file is as follows: A four line header that includes the owner of the job, the name of the job, the shell used to
run the job, and whether mail will be set after the job is executed. The header is followed by a cd command to the current directory and a
umask command to set the modes on any files created by the job. Then at copies all relevant environment variables to the spool file. When
the script is run, it uses the user and group ID of the creator of the spool file.
The time is 1 to 4 digits, with an optional following `A', `P', `N' or `M' for AM, PM, noon or midnight. One and two digit numbers are
taken to be hours, three and four digits to be hours and minutes. If no letters follow the digits, a 24 hour clock time is understood.
The optional day is either (1) a month name followed by a day number, or (2) a day of the week; if the word `week' follows, invocation is
moved seven days further off. Names of months and days may be recognizably truncated. Examples of legitimate commands are
at 8am jan 24
at -c -m 1530 fr week
at -s -m 1200n week
At programs are executed by periodic execution of the command /usr/libexec/atrun from cron(8). The granularity of at depends upon the how
often atrun is executed.
Error output is lost unless redirected or the -m flag is requested, in which case a copy of the errors is sent to the user via mail(1).
FILES
/usr/spool/at spooling area
/usr/spool/at/yy.ddd.hhhh.* job file
/usr/spool/at/past directory where jobs are executed from
/usr/spool/at/lasttimedone last time atrun was run
/usr/libexec/atrun executor (run by cron(8))
SEE ALSO atq(1), atrm(1), calendar(1), sleep(1), cron(8)DIAGNOSTICS
Complains about various syntax errors and times out of range.
BUGS
Due to the granularity of the execution of /usr/libexec/atrun, there may be bugs in scheduling things almost exactly 24 hours into the
future.
If the system crashes, mail is not sent to the user informing them that the job was not completed.
Sometimes old spool files are not removed from the directory /usr/spool/at/past. This is usually due to a system crash, and requires that
they be removed by hand.
