I'm looking at the output of "nm -t x jep.so" in AIX.
Found some symbols start with dot(".") like following:
.PyArg_ParseTuple T 0x00079880
What does this mean?
Thanks!

I want to insert a line "new line" into a file "Textfile.txt" at line number 3 in AIX.
Before insertion Textfile.txt looks like
one
two
four
After Insertion Textfile.txt looks like
one
two
new line
four
I have already done it on Linux how ever with AIX I am finding it not working with solution of Linux.
Surprisingly I couldn't find a simple solution for this problem anywhere.
I am using this command in Linux and is working
echo "target_node = ${arr[0]}"
echo "target_file = ${arr[1]}"
echo "target_line = ${arr[2]}"
echo "target_text = ${arr[3]}"
escape "$(ssh -f ${arr[0]} "sed -i "${arr[2]}i$(escape ${arr[3]})" ${arr[1]}; exit")"
To sum the previous bits of information written as comments:
Option -i doesn't exist in AIX!sed, use a temporary file; the syntax of command is more strict than in Linux.
sed '2a\
Insert this after the 2nd line' "$target_file" >"$target_file.tmp"
mv -- "$target_file.tmp" "$target_file"
Hi Thanks for the help,
I created script in such a way that it copies the file to linux update changes and movies to AIX.
I wrote the below code, which will extract the directory name along with the file name and I will use purge command on that extracted Text.
$ sear VAXMANAGERS_ROOT:[PROC]TEMP.LIS LOG/out=VAXMANAGERS_ROOT:[DEV]FVLIM.TXT
$ OPEN IN VAXMANAGERS_ROOT:[DEV]FVLIM.TXT
$ LOOP:
$ READ/END_OF_FILE=ENDIT IN ABCD
$ GOTO LOOP
$ ENDIT:
$ close in
$ ERROR=F$EXTRACT(0,59,ABCD)
$ sh sym ERROR
$ purge/keep=1 'ERROR'
The output is as follows:
ERROR = "$1$DKC102:[PROD_LIVE.LOG]DP2017_TMP2.LIS;27392 "
Problem here is --- Every time the directory length varies (Length may be 59 or 40 or some other value, but the directory and filename length will not exceed 59 characters in my system). So in the above output, the system is also fetching the Version number of that file number. So I am not able to purge the file along with the version number.
%PURGE-E-PURGEVER, version numbers not permitted
Any suggestion -- How to eliminate the version number from the output ?
I cannot use the exact length of the directory, as directory length varies everytime.... :(
The answer with F$ELEMENT( 0, ";", ABCD ) should work, as confirmed. I might script something like this:
$ ERROR = F$PARSE(";",ERROR) ! will return $1$DKC102:[PROD_LIVE.LOG]DP2017_TMP2.LIS;
$ ERROR = ERROR - ";"
$ PURGE/KEEP=1 'ERROR'
Not sure why you have the read loop. What you will get is the last line in the file, but assuming that's what you want.
While HABO explained it, some more explanations
Suppose I use f$search to check if a file exists
a = f$search("sys$manager:net$server.log")
then I find I it exists
wr sys$output a
shows
SYS$SYSROOT:[SYSMGR]NET$SERVER.LOG;9
From the help of f$parse I get
help lex f$parse arg
shows, among other things
`Specifies a character string containing the name of a field
in a file specification. Specifying the field argument causes
the F$PARSE function to return a specific portion of a file
specification.
Specify one of the following field names (do not abbreviate):
NODE Node name
DEVICE Device name
DIRECTORY Directory name
NAME File name
TYPE File type
VERSION File version number`
So I can do
wr sys$output f$parse(a,,,"DEVICE")
which shows
SYS$SYSROOT:
and also
wr sys$output f$parse(a,,,"DIRECTORY")
so I get
[SYSMGR]
and
wr sys$output f$parse(a,,,"NAME")
shows
NET$SERVER
and
wr sys$output f$parse(a,,,"TYPE")
shows
.LOG
the version is
wr sys$output f$parse(a,,,"VERSION")
shown as
;9
The lexicals functions can be handy, check it using
help lexical
it shows

I want to save the output of a program to a variable.
I use the following approach ,but fail.
$ PIPE RUN TEST | DEFINE/JOB VALUE #SYS$PIPE
$ x = f$logical("VALUE")
I got an error:%DCL-W-MAXPARM, too many parameters - reenter command with fewer parameters
\WORLD\
reference :
How to assign the output of a program to a variable in a DCL com script on VMS?
The usual way to do this is to write the output to a file and read from the file and put that into a DCL symbol (or logical). Although not obvious, you can do this with the PIPE command was well:
$ pipe r 2words
hello world
$ pipe r 2words |(read sys$pipe line ; line=""""+line+"""" ; def/job value &line )
$ sh log value
"VALUE" = "hello world" (LNM$JOB_85AB4440)
$
IF you are able to change the program, add some code to it to write the required values into symbols or logicals (see LIB$ routines)
If you can modify the program, using LIB$SET_SYMBOL in the program defines a DCL symbol (what you are calling a variable) for DCL. That's the cleanest way to do this. If it really needs to be a logical, then there are system calls that define logicals.
How do I get gvim to recognize sqlcomplete.vim commands?

Some points you could check:
:scriptnames shows plugin\sqlcomplete.vim
But the link you provided points to .../vim/runtime/autoload/sqlcomplete.vim, there is no .../vim/runtime/plugin/sqlcomplete.vim, and the version at vim.org also doesn't contains a /plugin file:
install details
Copy sqlcomplete.vim to:
.vim/autoload/sqlcomplete.vim (Unix)
vimfiles\autoload\sqlcomplete.vim (Windows)
For documentation:
:h sql.txt
Maybe you have installed it incorrectly.
The file on your link has version 12 at its header, while the latest version is 15. Try updating to the latest version
Note that this plugin does not define the SQLSetType command.
You could check that by simple searching the file the on link. And on its header:

Im having an issue writing a DCL in OpenVMS in that I need the DCL to call a command and capture its output (but not output the output to the screen) Later on in the DCL I then need to print that output I stored.
Heres an example:
ICE SET FASTER !This command sets my environment to the "Faster" environment.
The above command outputs this if executed directly in OpenVMS:
Initialising TEST Environment to FASTER
--------------------------------------------------------------------------------
Using Test Search rules FASTER
Using Test Search rules FASTER
--------------------------------------------------------------------------------
dcl>
So I created a DCL in an attempt to wrap this output in order to display a more simplified output. Heres my code so far:
!************************************************************************
$ !* Wrapper for setting ICE account. Outputs Environment
$ !************************************************************************
$ on error then goto ABORT_PROCESS
$ICE_DCL_MAIN:
$ ice set 'P1'
$ ICE SHOW
$ EXIT
$ABORT_PROCESS:
$ say "Error ICING to: " + P1
$ EXIT 2
[End of file]
In the lines above ICE SET 'P1' is setting the ice environment, but I dont want this output to be echoed to VMS. But what I do want is to write the output of $ICE SHOW into a variable and then echo that out later on in the DCL (most of which ive omitted for simplification purposes)
So what should be outputted should be:
current Test Environment is DISK$DEVELOPERS:[FASTER.DEVELOP]
Instead of:
Initialising TEST Environment to FASTER
--------------------------------------------------------------------------------
Using Test Search rules FASTER
Using Test Search rules FASTER
--------------------------------------------------------------------------------
current Test Environment is DISK$DEVELOPERS:[FASTER.DEVELOP]
Ive had a look through the manual and im getting a bit confused so I figured I tried here. Id appreciate any pointers. Thanks.
EDIT
Here is what ive come up with after the comments, the problem im having is when I connect to VMS using an emulator such as SecureCRT the correct output is echoed. But when I run the DCL via my SSH2 library in .NET it doesnt output anything. I guess thats because it closes the SYS$OUTPUT stream temporarily or something?
$ !************************************************************************
$ !* Wrapper for setting ICE account. Outputs Environment
$ !************************************************************************
$ on error then goto ABORT_PROCESS
$ICE_DCL_MAIN:
$ DEFINE SYS$OUTPUT NL:
$ ice set 'P1'
$ DEASSIGN SYS$OUTPUT
$ ice show
$ EXIT
$ABORT_PROCESS:
$ say "Error ICING to: " + P1
$ EXIT 2
[End of file]
EDIT 2
So I guess really I need to clarify what im trying to do here. Blocking the output doesnt so matter so much, im merely trying to capture it into a Symbol for example.
So in C# for example you can have a method that returns a string. So you'd have string myResult = vms.ICETo("FASTER"); and it would return that and store it in the variable.
I guess im looking for a similar thing in VMS so that once ive iced to the environment I can call:
$ environment == $ICE SHOW
But I of course get errors with that statement
The command $ assign/user_mode Thing Sys$Output will cause output to be redirected to Thing until you $ deassign/user_mode Sys$Output or next executable image exits. An assignment without the /USER_MODE qualifier will persist until deassigned.
Thing can be a logical name, a file specification (LOG.TXT) or the null device (NLA0:) if you simply want to flush the output.
When a command procedure is executed the output can be redirected using an /OUTPUT qualifier, e.g. $ #FOO/output=LOG.TXT.
And then there is piping ... .
You can redirect the output to a temp file and then print its content later:
$ pipe write sys$output "hi" > tmp.tmp
$ ty tmp.tmp
VMS is not Unix, DCL is not Bash: you can not easily set a DCL symbol from the output of a command.
Your ICE SHOW prints one line, correct? The first word is always "current", correct?
So you can create a hack.
First let me fake your ICE command:
$ create ice.com
$ write sys$output "current Test Environment is DISK$DEVELOPERS:[FASTER.DEVELOP]"
^Z
$
and I define a dcl$path pointing to the directory where this command procedure is
so that I can use/fake the command ICE
$ define dcl$path sys$disk[]
$ ice show
current Test Environment is DISK$DEVELOPERS:[FASTER.DEVELOP]
$
Now what you need, create a command procedure which sets a job logical
$ cre deflog.com
$ def/job/nolog mylog "current''p1'"
^Z
$
And I define a command "current" to run that command procedure:
$ current="#deflog """
Yes, you need three of the double quotes at the end of the line!
And finally:
$ pipe (ice show | #sys$pipe) && mysym="''f$log("mylog")'"
$ sh symb mysym
MYSYM = "current Test Environment is DISK$DEVELOPERS:[FASTER.DEVELOP]"
$
On the other hand, I don't know what you are referring to C# and Java. Can you elaborate on that and tell us what runs where?
You can try using: DEFINE /USER SYS$OUTPUT NL:.
It works only for the next command and you dont need to deassign.
Sharing some of my experience here. I used below methods to redirect outputs to files.
Define/Assign the user output and then execute the required command/script afterwards. Output will be written to .
$define /user sys$output <file_path>
execute your command/script
OR
assign /user <file_path> sys$output
execute your command/script
deassign sys$output
To re-direct in to null device like in Unix (mentioned in above answers), you can use 'nl:' instead of
define /user sys$output nl:
or
assign /user nl: sys$output
