In future posts, please post the current version of your script along with any matching error messages.
You are quite a long way adrift with syntax. Note that when assigning variables there is no space character either side of the equals sign.
This should get you past the syntax errors.
Now! I wonder where the number 112000 came from? The units of the output from "du -s" are in "512 byte blocks".
Using the unix in-line calculator "bc" I get a different value for the number of 512 byte chunks in a Gigabyte.
The units of "du -sk" are easier to work with. See the "man" page for "du".

:confused: Hi UNIX gurus,
I am facing a typical problem while assigining while assigining output of awk to a variable.
I have a fixed length file say myinputfile.txt
When I allow the value/output of an awk to be redirected to a file, it works fine. i.e.
awk "/^.{232}$acctNum/ {... (8 Replies)
greetings all,

Hi all,
Hope someone can help me out here.

Hi,
I am trying to assign a value using below command and it is assigning the command to the variable not the output of the command?

How can i assign the output to the variable instead of whole command?
This is inside my awk script (7 Replies)

df
DF(1) BSD General Commands Manual DF(1)NAME
df -- display free disk space
SYNOPSIS
df [-b | -h | -H | -k | -m | -g | -P] [-ailn] [-t] [-T type] [file | filesystem ...]
LEGACY SYNOPSIS
df [-b | -h | -H | -k | -m | -P] [-ailn] [-t type] [-T type] [file | filesystem ...]
DESCRIPTION
The df utility displays statistics about the amount of free disk space on the specified filesystem or on the filesystem of which file is a
part. Values are displayed in 512-byte per block counts. If neither a file or a filesystem operand is specified, statistics for all mounted
filesystems are displayed (subject to the -t option below).
The following options are available:
-a Show all mount points, including those that were mounted with the MNT_IGNORE flag.
-b Use (the default) 512-byte blocks. This is only useful as a way to override an BLOCKSIZE specification from the environment.
-g Use 1073741824-byte (1-Gbyte) blocks rather than the default. Note that this overrides the BLOCKSIZE specification from the environ-
ment.
-H "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number
of digits to three or less using base 10 for sizes.
-h "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number
of digits to three or less using base 2 for sizes.
-i Include statistics on the number of free inodes. This option is now the default to conform to Version 3 of the Single UNIX
Specification (``SUSv3'') Use -P to suppress this output.
-k Use 1024-byte (1-Kbyte) blocks, rather than the default. Note that this overrides the BLOCKSIZE specification from the environment.
-l Only display information about locally-mounted filesystems.
-m Use 1048576-byte (1-Mbyte) blocks rather than the default. Note that this overrides the BLOCKSIZE specification from the environ-
ment.
-n Print out the previously obtained statistics from the filesystems. This option should be used if it is possible that one or more
filesystems are in a state such that they will not be able to provide statistics without a long delay. When this option is speci-
fied, df will not request new statistics from the filesystems, but will respond with the possibly stale statistics that were previ-
ously obtained.
-P Use (the default) 512-byte blocks. This is only useful as a way to override an BLOCKSIZE specification from the environment.
-T Only print out statistics for filesystems of the specified types. More than one type may be specified in a comma separated list.
The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action should not be taken. For
example, the df command:
df -T nonfs,mfs
lists all filesystems except those of type NFS and MFS. The lsvfs(1) command can be used to find out the types of filesystems that
are available on the system.
-t If used with no arguments, this option is a no-op (Mac OS X already prints the total allocated-space figures). If used with an argu-
ment, it acts like -T, but this usage is deprecated and should not be relied upon.
ENVIRONMENT
BLOCKSIZE If the environment variable BLOCKSIZE is set, the block counts will be displayed in units of that size block.
BUGS
The -n and -t flags are ignored if a file or filesystem is specified.
LEGACY DESCRIPTION
The "capacity" percentage is normally rounded up to the next higher integer. In legacy mode, it is rounded down to the next lower integer.
When the -P option and the -k option are used together, sizes are reported in 1024-blocks. In legacy mode, when the -P option and -k option
are used together, the last option specified dictates the reported block size.
The -t option is normally a no-op (Mac OS X already prints the total allocated-space figures). In legacy mode, it is equivalent to -T.
For more information about legacy mode, see compat(5).
