TIME=12:59

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)
In awk, how do I print all fields with a specified output field separator?
I have tried the following, which does not print the output FS:

jfs_mkfs
jfs_mkfs(8) JFS file system creation jfs_mkfs(8)NAME
jfs_mkfs - create a JFS formatted partition
SYNOPSIS
jfs_mkfs [options] device [ blocks ]
DESCRIPTION
jfs_mkfs is used to create (format) a JFS partition. jfs_mkfs must be run as root.
device is the special file name corresponding to the actual device (e.g. /dev/hdb1) on which a JFS file system and/or JFS journal will be
created. blocks is the number of blocks to be used for the file system. If omitted, jfs_mkfs automatically figures the file system size.
The default block size is 4096.
WARNING
jfs_mkfs will destroy all data on the specified device!
OPTIONS -c Check the device for bad blocks before building the file system.
-j journal_device
Create the external JFS journal on journal_device , create the JFS file system on device , and attach the external journal to the
file system.
-J journal-options
Create the JFS journal on its own device or attach an external JFS journal to the JFS file system using options specified on the
command-line. The following journal options are supported:
journal_dev
Create an external JFS journal on the given device.
device=external-journal
Attach an existing external JFS journal located on external-journal to the JFS file system that will be created on
device. The external journal must already have been created using the command
jfs_mkfs -J journal_dev external-journal
Attach the external journal to the file system being created by using the command
jfs_mkfs -J device=external-journal device
Instead of specifying a device name directly, external-journal can also be specified by either LABEL=label or UUID=UUID
to locate the external journal by either the volume label or UUID stored in the JFS external log superblock at the start
of the journal. Use jfs_tune(8) to display a journal device's volume label and UUID. (See the -l, -L, and -U options
of jfs_tune(8).)
Only one of the journal_dev or device= options can be given per jfs_mkfs issuance.
-L volume_label
Set the volume label for the newly formatted device.
If -L volume_label is used along with -J journal_device, the volume label of the specified external journal device will be set to
volume_label. Otherwise, the volume label of the JFS file system will be set to volume_label.
-O Provide case-insensitive support for compatibility with OS/2.
-q Quiet execution - do not ask for confirmation before creating the file system.
-s log_size
Set the log size (in megabytes) of the inline log. If the -s option is not used, the default log size is 0.4% of the aggregate
size.
-V Print version information and exit (regardless of any other chosen options).
EXAMPLES
Format 3rd partition on 2nd hard disk with the volume label "JFS_hdb3":
jfs_mkfs -L JFS_hdb3 /dev/hdb3
Format 5th partition on 1st hard disk, verifying each block created:
jfs_mkfs -c /dev/hda5
Format 3rd partition on 2nd hard disk as external journal, format 4th partition on 1st hard disk as JFS file system, and attach the exter-
nal journal to the file system:
jfs_mkfs -j /dev/hdb3 /dev/hda4
