What is the exact FETCH command that is used to read only the text body of message 1?
I tried this below and variations of it but it says BAD Error in IMAP and Unknown command.
**FETCH 1:1 (BODY[HEADER.FIELDS (TEXT)]**
Im executing this in Ubuntu on a terminal for my upcoming exam.
Try _ FETCH 1 (BODY[TEXT]). Why do you have asterisks around your command? You find the possible arguments to the FETCH command in RFC 3501. You can also play around with the interactive tool that I wrote.

I am a beginner to programming. I am trying to run a simulation of a combustion chamber using reactingFoam.
I have modified the counterflow2D tutorial.
For those who maybe don't know OpenFOAM, it is a programme built in C++ but it does not require C++ programming, just well-defining the variables in the files needed.
In one of my first tries I have made a very simple model but since I wanted to check it very well I set it to 60 seconds with a 1e-6 timestep.
My computer is not very powerful so it took me for a day aprox. (by this I mean I'd like to find a solution rather than repeating the simulation).
I executed the solver reactingFOAM using 4 processors in parallel using
mpirun -np 4 reactingFOAM -parallel > log
The log does not show any evidence of error.
The problem is that when I use reconstructPar it works perfectly but then I try to watch the results with paraFoam and this error is shown:
From function bool Foam::IOobject::readHeader(Foam::Istream&)
in file db/IOobject/IOobjectReadHeader.C at line 88
Reading "mypath/constant/reactions" at line 1
First token could not be read or is not the keyword 'FoamFile'
I have read that maybe some files are empty when they are not supposed to be so, but I have not found that problem.
My 'reactions' file have not been modified from the tutorial and has always worked.
edit:
Sorry for the vague question. I have modified it a bit.
A typical OpenFOAM dictionary file always contains a Foam::Istream named FoamFile. An example from a typical system/controlDict file can be seen below:
FoamFile
{
version 2.0;
format ascii;
class dictionary;
location "system";
object controlDict;
}
During the construction of the dictionary header, if this Istream is absent, OpenFOAM ceases its operation by raising an error message that you have experienced:
First token could not be read or is not the keyword 'FoamFile'
The benefit of the header is possibly to contribute OpenFOAM's abstraction mechanisms, which would be difficult otherwise.
As mentioned in the comments, adding the header entity almost always solves this problem.
I want to use the Github API in a script and I want to use it as an experience to get better using Perl6. However, I cannot even get a simple proof of concept to work.
Through some testing I realized that Github requires that you supply a valid user agent so I turned to HTTP::UserAgent. No matter what I try, I get the following error:
Internal Error: 'server returned no data'

There is even an example in the the repo that doesn't seem to work for me.
#!/usr/bin/env perl6
use v6;
use HTTP::UserAgent;
my $ua = HTTP::UserAgent.new;
$ua.timeout = 1;
my $response = $ua.get('https://github.com');
if $response.is-success {
say $response.content;
} else {
die $response.status-line;
}
Any tips on how to connect to Github via Perl 6? I really love many aspects of the language but this type of thing is discouraging.
EDIT: I went on #perl6 irc and no one was able to reproduce this on other OSes. I got it to work on Debian. The issue seems to be with OS X
Although in alpha stage, WebServices::GitHub is perfectly serviceable. You can use it to download user information, or you can use my fork if you want to interact with issues. This program, for instance, is used to download some issues from a particular repo.
I've tried to find a table with the definition for each COMPSTAT (related to the tool Control-M workload Automation) return code but without any success.
Can anyone tell me if such a table exists?
Thank you.
It's the return code from whatever task was being executed at that time. By convention, a zero value means 'OK', and anything non-zero means an error of some kind.
Different utilities (i.e. external commands) have different possible return codes, so if the command were SCP then you would look up the code in the SCP documentation, and find that for example, '67' meant 'key exchange failed'.
There is no table that contains the definition of each COMPSTAT return code.
OSCOMPSTAT stand for Control-M Operating System Completion Status.
The value of COMPSTAT is set by the exit code of the command that was called.
Example:
After calling the command [cat file1.txt] the value of COMPSTAT will be:
0 if the file "file1.txt" is found
1 if the file "file1.txt" is not found
After calling the command [ctmfw] the value of COMPSTAT will be:
0 if the specified file is found
7 if the specified file is not found
All, I am running the following script to load the data on to the Oracle Server using unix box and sqlldr. Earlier it gave me an error saying sqlldr: command not found. I added "SQLPLUS < EOF", it still gives me an error for unexpected end of file syntax error on line 12 but it is only 11 line of code. What seems to be the problem according to you.
#!/bin/bash
FILES='ls *.txt'
CTL='/blah/blah1/blah2/name/filename.ctl'
for f in $FILES
do
cat $CTL | sed "s/:FILE/$f/g" >$f.ctl
sqlplus ID/'PASSWORD'#SERVERNAME << EOF sqlldr SCHEMA_NAME/SCHEMA_PASSWORD control=$f.ctl data=$f EOF
done
sqlplus will never know what to do with the command sqlldr. They are two complementary cmd-line utilities for interfacing with Oracle DB.
Note NO sqlplus or EOF etc required to load data into a schema:
#!/bin/bash
#you dont want this FILES='ls *.txt'
CTL_PATH=/blah/blah1/blah2/name/'
CTL_FILE="$CTL_PATH/filename.ctl"
SCHEMA_NM=SCHEMA_NAME
SCHEMA_PSWD=SCHEMA_PASSWORD
for f in *.txt
do
# don't need cat! cat $CTL | sed "s/:FILE/$f/g" >"$f".ctl
sed "s/:FILE/$f/g" "$CTL_FILE" > "$CTL_PATH/$f.ctl"
#myBad sqlldr "$SCHEMA_NAME/$SCHEMA_PASSWORD" control="$CTL_PATH/$f.ctl" data="$f"
sqlldr $SCHEMA_USER/$SCHEMA_PASSWORD#$SERVER_NAME control="$CTL_PATH/$f.ctl" data="$f" rows=10000 direct=true errors=999
done
Without getting too philosophical, using assignments like FILES=$(ls *.txt) is a bad habit to get into. By contrast, for f in *.txt will deal correctly for files with odd characters in them (like spaces or other syntax breaking values). BUT the other habit you do want to get into is to quote all variable references (like $f), with dbl-quotes : "$f", OK? ;-) This is the otherside of protection for files with spaces etc embedded in them.
In the edit update, I've varibalized your CTL_PATH and CTL_FILE. I think I understand your intent, that you have 1 std CTL_FILE that you pass thru sed to create a table specific .ctl file (a good approach in my experience). Note that you don't need to use cat to send a file to sed, but your use to create a altered file via redirection (> $f.ctl) is very shell-like too.
In 2nd edit update, I looked here on S.O. and found an example sqlldr cmdline that has the correct syntax and have modified to work with your variable names.
To finish up,
A. Are you sure the Oracle Client package is installed on the machine
that you are running your script on?
B. Is the /path/to/oracle/client/tools/bin included in your working
$PATH?
C. try which sqlldr. If you don't get anything, either its not
installed or its not in the path.
D. If not installed, you'll have to get it installed.
E. Once installed, note the directory that contains the sqlldr cmd.
find / -name 'sqlldr*' will take a long time to run, but it will
print out the path you want to use.
F. Take the "path" part of what is returned (like
/opt/oracle/11.2/client/bin/ (but not the sqlldr at the end), and
edit script at 2nd line with
(Txt added to appease the S.O. Formatter ;-) )
export ORCL_PATH="/path/you/found/to/oracle/client"
export PATH="$ORCL_PATH:$PATH"
These steps should solve any remaining issues. If this doesn't work, see if there is someone where you work that understands your local computing environment that can help explain any missing or different steps.

Here is a basic script with getopt command and assigned variables.
If someone were to type in
MyScript -a
with no words or numbers added after the -a, then an error message would pop up! The same happens if you replace -a with any other assigned variables. If I wanted no error message to appear, how would I go about doing this?
Hints/advice is preferred over a simply strict answer!
From the bash manual:
getopts can report errors in two ways. If the first character of optstring is a colon, silent error reporting is used. In normal operation diagnostic messages are printed when invalid options or missing option arguments are encountered. If the variable OPTERR is set to 0, no error messages will be displayed, even if the first character of optstring is not a colon.
Since you tag the question with Unix and don't mention bash, you may or may not be so lucky, but the answer is to read the manual page carefully.
