The .file.swp file is the editing state file for vi (or vim) for the file named file. If vi died or our system died while you were editing the file, the way to recover your file is to execute the following commands:
You can then compare file and _file to see if you got the version you wanted. Then you should remove .file.swp before you edit the file again.
Since the swap file is a binary file (not a text file), you probably don't want to use the mv command you tried. If you haven't modified the file after moving the swap file to your original file name, you can move it back to its swap file name and then try the steps I outlined above.

Hi,
I am using ksh.
I have to find wether data file has EOL or not. as per my knowledge we can easily find by checking each character. But this is a tedious job as per my requirement because my data file size is very big . It may be in 25-30 MB.
So please advice me how i can check wether... (4 Replies)
Hi,
I want to check whether file has EOL or NOEOL before opening this file in VI editor. My file is very big its in terms of 15-20 MB.
I am using ksh for this.
When we opened the file in vi editor, normally at last line we are able to see whether this is eol or noeol file. But i does want... (1 Reply)
Hello and thanks in advance.
I have a Sun box with raid 1 on the O/S disks using solaris svm.
I want to unmirror my swap partition, and add the slice on the second disk as an additional swap device. This would give me twice as much swap space.
I have been warned not to do this by some... (3 Replies)
Hi All,
I am new to shell scripting but have successfully created some of my own scripts using awk and sed. However, I have come across a problem that I cannot solve on my own and have not been able to find a good example that relates to what I am trying to do.

Hi
I have an integrity machine rx7620 and rx8640 running hp-ux 11.31. I'm planning to fine tune the system:
- I would like to know when does the memory swap space spill over to the device swap space?
- And how much % of memory swap utilization should be specified (swap space device... (6 Replies)
The only way I know of is manually as follows:
To remove for example ^M from a file:
- vi the file name that has ^M at the end of each line.
- Hit <Esc>
- Type :g/
- Hold the CNTRL key and press V and M then release the CNTRL key At the buttom you should see this by now: ... (3 Replies)

swapmem_on(5) OBSOLETE swapmem_on(5)NAME
swapmem_on - OBSOLETE kernel tunable parameter
DESCRIPTION
The tunable is obsolete. Processes will always be allowed to use pseudo-swap space if it is available.
In previous versions of HP-UX, system configuration required sufficient physical swap space for the maximum possible number of processes on
the system. This is because HP-UX reserves swap space for a process when it is created, to ensure that a running process never needs to be
killed due to insufficient swap.
This was difficult, however, for systems needing gigabytes of swap space with gigabytes of physical memory, and those with workloads where
the entire load would always be in core. This tunable was created to allow system swap space to be less than core memory. To accomplish
this, a portion of physical memory is set aside as "pseudo-swap" space. While actual swap space is still available, processes still
reserve all the swap they will need at fork or execute time from the physical device or file system swap. Once this swap is completely
used, new processes do not reserve swap, and each page which would have been swapped to the physical device or file system is instead
locked in memory and counted as part of the pseudo-swap space.
WARNINGS
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
