I am using this code to insert something into a csv file:
awk -F";" -v url=$url -v nr=$nr 'NR==nr{$2=url$2}1' file
Why do I get the output
field1 field2
instead of
field1;field2
I have given -F";", so the field separator should surely be ";". (1 Reply)

vfs_prealloc
VFS_PREALLOC(8)VFS_PREALLOC(8)NAME
vfs_prealloc - preallocate matching files to a predetermined size
SYNOPSIS
vfs objects = prealloc
DESCRIPTION
This VFS module is part of the samba(7) suite.
The vfs_prealloc VFS module preallocates files to a specified size each time a new file is created. This is useful in environments where
files are of a predetermined size will be written to a disk subsystem where extending file allocations is expensive.
This module is stackable.
OPTIONS
prealloc:EXT = BYTES
Preallocate all files with the extension EXT to the size specified by BYTES.
The following suffixes may be applied to BYTES:
o K - BYTES is a number of kilobytes
o M - BYTES is a number of megabytes
o G - BYTES is a number of gigabytes
EXAMPLES
A process writes TIFF files to a Samba share, and the is known these files will almost always be around 4 megabytes (4194304 bytes):
[frames]
path = /data/frames
vfs objects = prealloc
prealloc:tiff = 4M
CAVEATS
vfs_prealloc is not supported on all platforms and filesystems. Currently only XFS filesystems on Linux and IRIX are supported.
VERSION
This man page is correct for version 3.0.25 of the Samba suite.
AUTHOR
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
