Command to output ones (like zero-fill), with progress indicator
Well, I was originally going to post this snippet in the original thread titled "how to output ones endlessly like /dev/zero", but that topic was closed without an efficient answer.
This command seems to get me about 500MByte/min, though this is with a 1.5TB 'green' drive running only at 5400rpm so I imagine it'd be faster in most other cases.
I'm looking for a way in Korn shell to zero fill (or space fill) the output from df so that it will sort properly.
"Raw" output from df -k:
df -k

Can anybody suggest you a good script to show progress of a process.

while true ; do
for i in \| \/ \- \\ \| \/ \- \\
do
echo "\b\b$i \c"
sleep 1
done

Hi,
I want to use zenity --progress and also put the output to the terminal.
I tried using the tee command but that puts the output to the terminal first and then shows the zenity progress dialog.

WREN(3) Library Functions Manual WREN(3)NAME
wren, ata - hard disk interface
SYNOPSIS
bind #H[drive] /dev
bind #w[target[.lun]] /dev
/dev/hd0disk
/dev/hd0partition
/dev/sd0disk
/dev/sd0partition
...
DESCRIPTION
The hard disk interfaces (wren, #w, is a SCSI disk; ata, #H, is an IDE or ATA disk) serve a one-level directory giving access to the hard
disk partitions. The parameter to attach defines the numerical SCSI target and logical unit number or the IDE drive number to access.
Both default to zero.
Each partition name is prefixed by hd and the numeric drive identifier. The partition always exists and covers the entire disk. The size
of each partition as reported by stat(2) is the number of bytes in the partition, so the size of is the size of the entire disk.
The partition also always exists; it is the last block on the disk for SCSI, second to last for IDE. If it contains valid partition data,
those partitions will be visible as well. Every time the device is bound, the partitions are updated to reflect any changes in the parti-
tion file.
The format of the partition file is the string
plan9 partitions
on a line, followed by partition specifications, one per line, consisting of a name and textual strings for the block start and limit for
each partition on the disk.
The program prep(8) writes the partition table for the disk; its use is preferred to writing it by hand.
