psrchive is built under 64bit and with gfortran as the fortran compiler. Note that they require a 64bit gfortran compiled pgplot. I will start by building psrchive since it well build its dependencies automatically.

—–PSRCHIVE—————
Set $PSRHOME to /usr/share/astro/psrhome/ this is the directory for all the softwares.

Add $PSRHOME/bin to your $PATH variable

$ cd $PSRHOME

Unzip psrcat in the directory (psrcat available at http://www.atnf.csiro.au/people/pulsar/psrcat/download.html). Then add in .cshrc setenv PSRCAT_FILE $PSRHOME/psrcat/psrcat.db

$ mkdir src && cd src

$ git clone git://git.code.sf.net/p/psrchive/code psrchive

$ cd psrchive

$ ./bootstrap

$ ./configure –prefix=$PSRHOME F77=gfortran

Then psrchive will complain about not having required packages. It generetes csh scripts under packages for installation and we will use those

$ cd packages

$./pgplot.csh

Remember to add to .cshrc $PGPLOT_DIR and $PGPLOT_FONTS as the script suggests. In my case it is

setenv PGPLOT_DIR $PSRHOME/pgplot/

setenv PGPLOT_FONTS $PGPLOT_DIR/grfont.dat

You should also add $PGPLOT_DIR to your LD_LIBRARY_PATH in .cshrc.

$./fftw.csh

$./cfitsio.csh

$PSRHOME/x86_64-linux/src/cfitsioTake notes of where the cfitsio source is located. We will need it later. In my case it is under $PSRHOME/src/cfitsio

$source ~/.cshrc

this step validates the changes made to the environmental variables.

$./tempo2.csh

This will install tempo2 but likely pgplot will not be linked and henceforth this is not yet a fully functional tempo2. But it does have the components
that psrchive needs. The tempo2 linked with pgplot will be built seperately later.

You should set your $TEMPO2 variable to the tempo2 runtime directory. In my case it is $PSRHOME/tempo2

$ cd ..

This should bring you back to the psrchive folder where configure is located. Now rerun ./configure. It should not complain about fftw, cfitsio, tempo2 or pgplot

./configure –prefix=$PSRHOME F77=gfortran –with-cfitsio-dir=$PSRHOME/src/cfitsio

If you are still having trouble, look at http://psrchive.sourceforge.net/third/packages.shtml. When I did it it can find everything but cfitsio so I fed in the
–with-cfitsio-dir directory. Now we are ready to build it.

$ make

$ make check

$ make isntall

Done! the binaries should locate in $PSRHOME/bin . You should add it to your $PATH variable.

to select VERTICALLY (column mode) in vi or vim or kate editors

Published by jweisber on 2016-02-18

suppose you want to select a column (or more) in a file?

in vi or vim:

1. select a corner of desired region

2.  contol v  (start Visual block)

3. move cursor to opposite corner and

4. you will see the desired box highlighted!

5. then do what you will with that highlighted region. eg  d(elete)

6. to paste it elsewhere, move cursor to desired location and p(aste)

(Note if I tried y(ank) instead of d, I got full lines in buffer rather than desired box)

Added 2018 Jul 29: For kate, cntrl-shift-b enables similar block mode for delete at least.  However, multiple write doesnt come until v 4.12 and we seem to have v3.4. –jmw
