I am newbie to Seadas.I have installed seadas 7.5.1 GUI ,I want to work on seadas  by command mode ,so I installed IDL. Is License is necessary for IDL to work in command mode..

You don't need IDL.  SeaDAS has not required IDL since prior to version 7.0

I gave command as seadas em  in terminal .It gave msg as:
seadas: command not found

You appear to be using outdated documentation.  Have a look at the current installation documention, but note that this also includes processing software that you may not need. The -em option was for SeaDAS pre-7 versions that used an IDL GUI and is no longer used.   To run the SeaDAS 7 GUI from a terminal, you must either add the SeaDAS 7 bin directory to the PATH environment variable (consult an introduction to the linux command-line for details) or give a the executable filename (e.g., seadas) with the path (e.g., $SEADASPATH/bin/seadas).

Since you appear to be new to the linux/bash command-line, you will find it helpful to spend a few hours getting comfortable with the basic command-line procedures used in the above tutorial.   Linux Command is a good starting point, but there are many good resources available in English and many other languages if you are not comfortable with English documentation.

To install and setup the command line programs read the "SeaDAS Processing Programs" and the "Command Line Configuration" sections of this web page.

Thankyou for the responses don and gnwii.
yes I followed the procedure given by don and I saw the linux commands.
I opened seadas in termainal and gave l2gen command as below

itra@itra-PC:~/seadas-7.5.1/bin$ seadas
l2gen ifile=/home/itra/Data/sentinel-2/S2B_MSIL1C_20181005T044659_N0206_R076_T45QUB_20181006T091548.SAFE/manifest.safe ofile=/home/itra/Data/seadas_outputs/Sentinel2_op/test_msi.L2

no processing ..no output. Am I missing anything in this command..

The command should be:

itra@itra-PC:~/seadas-7.5.1/bin$  ./l2gen ifile=/home/itra/Data/sentinel-2/S2B_MSIL1C_20181005T044659_N0206_R076_T45QUB_20181006T091548.SAFE/manifest.safe ofile=/home/itra/Data/seadas_outputs/Sentinel2_op/test_msi.L2


Note: without "seadas"

I am assuming that you installed the data files for Sentinel 2B.  If not, use this command:


$ install_ocssw.py --msis2b

don
I already installed that one .
