I’ve got multiple-line text files of (sometimes) tab-delimited data. I’d like to output the file so I can glance over it – so I’d like to only see the first 80 characters of each line (I designed the text file to put the important stuff first on each line).
I am working on mac with sed, perl, awk, bash..
I want to apply grep on particular column in column command.
Is it possible to copy the whole rows of File1 in a new File3 following the instruction given by File2 by using a simple bash script using sed or awk?
How to create a new file merging selective columns from two separate files using awk? Without messing up the elements orders of BOTH files.
I’m colorizing the header of a table formatted with column -ts $'t'

how can I achieve this?
thanks
I have three files file1.txt, file2.txt, file3.txt and they are of same format.
I have two files with approximately 12900 and 4400 entries respectively, that I want to join. The files contain location information for all landbased weather observing stations around the globe.
The largest file is updated biweekly, and the smaller once a year or so. The original files can be found here (http://www.wmo.int/pages/prog/www/ois/volume-a/vola-home.htm and
http://weather.rap.ucar.edu/surface/stations.txt). The files I have are already manipulated by me with some mixed awk, sed, and bash script. I use the files to visualize data using the
GEMPAK package, that is freely available from Unidata. The largest file will work with GEMPAK, but only not with its full capability. For this a join is needed.
I have a file as given below
