Operating Systems HP-UX How To Rotate A File in HP-UX? Post 302869319 by vbe on Wednesday 30th of October 2013 05:42:59 AM

If you move the file, the writing will continue in the moved file...
I either stop the writing ( daemon ...) and restart or if cannot, do:
Code:
mv file.last file.beforelast
cp -p file  file.last
> file   # zero the file...
#gzip if you wish:

put in a script so it is executed flawlessly so I have less loss possible and choose a moment I know with minimum risk of activity to execute the code...

NAME
pfsrotate - Rotate images 90 degrees. SYNOPSIS
pfsrotate [--r] [--help] DESCRIPTION
Use this command to rotate images from a stream of pfs. This command is useful for output on hardcopy devices with aspect ratios opposite to the input image. By default, the image is rotated clockwise. The --r option may be used to rotate the image counter-clockwise instead. OPTIONS
--r, -r Rotate the image counter-clockwise instead of clockwise. EXAMPLES
pfsin memorial.hdr | pfsrotate -r | pfsout memorial_gc.hdr Rotate memorial image 90 degrees counter-clockwise and save to memorial_gc.hdr. NOTES
To rotate an image 180 degrees, use pfsflip(1) with both the --h and --v options specified. SEE ALSO
pfsin(1) pfsout(1) pfsflip(1) BUGS
Please report bugs and comments to Alexander Efremov <aefremov@mpi-sb.mpg.de>. pfsrotate(1)
