egrep to filter out lines in a text file NOT cointaining certain strings

this worked for me:

egrep '^str2|str1' file.txt

winscp delete after successful transfer (put/get)

I've been using WinScp and a script to compress files at maximum compressiĆ³n, name the file as name_YYMMDD-HHMM.rar, and send them to a remote server; then I wanted to delete local files after a successful transfer. Here's my batch file (it works on WinXP). :

;FOR /F "tokens=1-4 delims=/ " %%I IN ('DATE /t') DO SET mydate=%%K%%J%%I
;
;FOR /F "eol=; tokens=1-2 delims=: " %%a IN ('TIME /t') DO SET mytime=%%a%%b
;
;ECHO The value is "%mydate% %mytime%"
;
;set varname=myname-%mydate%-%mytime%.rar
;
;rar m -m5 %varname% "FolderWithFilesToCompress\*.jpg"
;echo %varname%

start /min winscp.exe /console /command "option batch on" "open lab@64.150.188.62" "option confirm off" "put -delete %varname%" "exit"


To call the batch file automatically in a minimized mode, I call from window's Task Scheduler this vbs script (the last 0 means minimized):

Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\path\to\batch\mybatch.bat" & Chr(34), 0
Set WinScriptHost = Nothing

And here the documentarion on WinScp

Script Commands

In its scripting functionality, WinSCP supports set of commands described below.

You can see the very same help for the commands as shown here, if you type command help directly in console.

General Syntax

Command parameters that include space(s) have to be enclosed in double-quotes. To use double-quote literally, double it:

put "file with spaces and ""quotes"".html"

You can use environment variables in the commands, with syntax %NAME%1):

put "%FILE_TO_UPLOAD%"

You can reference script arguments (passed on command-line using parameter /parameter) using syntax %N%, where N is ordinal number of argument1):

put "%1%"

Note that WinSCP treats filenames in case sensitive manner. So even if your server treats filenames in case insensitive manner, make sure you specify case properly2).

Advertisements:

call

With SFTP and SCP protocols, executes arbitrary remote shell command. With FTP protocol, executes a protocol command.

call 

If current session does not allow execution of arbitrary remote command separate shell session will be automatically opened.

The command must not require user input.

sed script to strip ^M characters

this may also be handy, to strip ^M characters:
(from http://www.computing.net/answers/unix/remove-m-and-line-feeds/6934.html)
anupam May 23, 2005 at 21:11:55 Pacific

Hi..to remove ^M, give the command :
sed -e 's/^M//g' filename
you will have to write the control-M as follows : first press control-V,then control-M,this will show the correct control-M on the command line.
For removing the linefeeds,try this :
sed -e 's/.$//g' filename
this will remove the last character from the line,which happens to be the line feed.

installink XEphem on Ubuntu

had I found this link earlier, i wouldn't have wasted so much time and effort:

http://www.tc.umn.edu/~brams006/xephem_ubuntu.html

How to Compile XEphem on Ubuntu Linux

Following is a (hopefully) painless guide to compiling the excellent astronomy program named XEphem (http://www.clearskyinstitute.com/xephem/) on the Ubuntu linux distribution. Though we now have Stellarium and KStars, XEphem has some unique features and the source code is free for personal/educational use (check the URL for precise terms). In addition, it doesn't require a higher-end OpenGL graphics card. It'll run well on a fairly modest machine. I've tested these steps on Ubuntu 10.04 Lucid Lynx and they worked for me without any trouble.

(1) Preliminaries & Packages.

Use either "sudo apt-get install" or Synaptic to pull down (or verify that you already have) the following packages installed:

gcc
lesstif2-dev
libc6-dev
libxmu-dev
make

Since I embarked on this document (perhaps in 2005), I've noticed a couple changes with the Ubuntu packages. When you install the gcc compiler it sets up a symlink automatically from /usr/bin/gcc to the /usr/bin/gcc-{version number} executable. In the past, you may have needed to create this symlink yourself. For the newbies: 'cd /usr/bin', then 'ln -s gcc-4.4 gcc' or whatever was the gcc version.

If you'd rather compile with libmotif3 and libmotif3-dev (instead of the lesstif2 and lesstif2-dev respectively), you'll need to go into Synaptic (or edit /etc/apt/source.list manually), enable the Non-free Multiverse repository, and install those packages instead. There are some licensing politics surrounding motif.

In any case, I've successfully compiled XEphem 3.7.4 with gcc-4.x and the LGPL lesstif2/lesstif2-dev Ubuntu maintained packages, as well as the libmotif3/libmotif3-dev alternative.

(2) Get the XEphem source code.

Go here: http://www.clearskyinstitute.com/xephem/. Download it to a directory, for instance your user directory, and ungzip/untar it. It'll be in a directory named "xephem-3.7.4" (depending on version number).

(3) Make a change to the xephem-3.7.4/libz/Makefile

This file may initially be read-only, so be sure to chmod +w it if necessary. I noticed this issue with the source for XEphem 3.7.1 and 3.7.2 as well. There's a couple things missing from the makefile in the xephem-3.7.4/libz/Makefile file. Make sure the top of that file includes this:

CC = gcc
CLDFLAGS = -g
CFLAGS = $(CLDFLAGS) -Wall -O2
LDFLAGS =

And the bottom of the file needs to have "gcc" specified rather than cc.:

testzlib: testzlib.o libz.a
gcc $(LDFLAGS) -o testzlib testzlib.o libz.a

(4) Compile XEphem.

Whether you're using motif or lesstif, the XEphem makefiles expect some value for "MOTIF=" in order to compile. Go to the xephem-3.7.4/GUI/xephem directory. Issue this:

make MOTIF=/usr/lib/

XEphem should now successfully compile after a minute or so, depending on the speed of your hardware.

(5) Run and test.

Go to /xephem-3.7.4/GUI/xephem and type "./xephem" to execute. The first things you might want to do is to set the observer location to your own and confirm that your time/zone information is correctly indicated.

I like to create a KDE desktop icon for XEphem. From the KDE desktop, right-click and create a new link to an application. Go to the directory /xephem-3.7.4/GUI/xephem and select the xephem executable, change the icon to the XEphem.png file there. Then make sure the working directory is set to /xephem-3.7.4/GUI/xephem (or wherever you actually installed it).

As of Ubuntu 10.04 I decided to switch to Gnome. I see that the Gnome desktop application launcher doesn't include a "working directory" setting. Unless XEphem is executed from the path it resides in, some components may be improperly pathed. Being less experienced with Gnome, I'm not sure if this is the best approach, but it was awfully simple:

In the ~/xephem3.7.4/ directory I created a simple script called xephem.sh, and chmod +x to it. Here's the contents of the script:

cd /home/{my user directory}/xephem-3.7.4/GUI/xephem
./xephem

I then aimed the Gnome desktop launcher at this script, and used the icon here: /xephem-3.7.4/GUI/xephem/XEphem.png.

Enjoy!

missing files

when installing from source file, using make, and it says error "file not found" check apt-file utility for which package you need to install


FROM: http://superuser.com/questions/10997/find-what-package-a-file-belongs-to-in-ubuntu-debian

I frequently find myself missing a program, man page, or other file when working on my Ubuntu 8.04 system. Is there any simple way to look up what package contains a given file (whether it is installed already or not)? Maybe some obscure option for apt or dpkg?

apt-file search filename

or

apt-file search /path/to/file


if you need apt-file, use:

apt-get install apt-file

you may also want to update its database:

sudo apt-file update

running a windows scheduled task minimized

also you can do start /min \path\to\program.exe inside the batch, to run programs from the batch file in minimized mode


You could run it silently using a Windows Script file instead. The Run Method allows you running a script in invisible mode. Create a .vbs file like this one

Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Scheduled Jobs\mybat.bat" & Chr(34), 0
Set WinScriptHost = Nothing

and schedule it. The second argument in this example sets the window style. 0 means "hide the window."

Complete syntax of the Run method:

 object.Run(strCommand, [intWindowStyle], [bWaitOnReturn])

Arguments:

  • object: WshShell object.
  • strCommand: String value indicating the command line you want to run. You must include any parameters you want to pass to the executable file.
  • intWindowStyle: Optional. Integer value indicating the appearance of the program's window. Note that not all programs make use of this information.
  • bWaitOnReturn: Optional. Boolean value indicating whether the script should wait for the program to finish executing before continuing to the next statement in your script. If set to true, script execution halts until the program finishes, and Run returns any error code returned by the program. If set to false (the default), the Run method returns immediately after starting the program, automatically returning 0 (not to be interpreted as an error code).
