Thank you, Ravinder, it works, but not for all files.
Sometimes I get only

EEEEE


It may be an issue with the formatting, which I'm currently investigating....

Hi,
I have a text file like this

6.0000E-02 0.00000E+00 0.0000 0.00000E+00 0.0000
7.0000E-02 5.00000E-10 1.0000 5.00000E-10 1.0000
8.0000E-02 3.00000E-09 0.4082 ...

If I use

if [ -f "$file_name" ]; then
echo File $file_name Found
else
echo File $file_name Not Found
fi

then it works in the opposite direction I hae the impression, i.e....

So how the final script should be e.g. in the first case?

Hi,
I have the following script under bash

if(${a}>${b})
echo 1
else
echo 2

Hi all,
I'm struggling :wall: to make a an if statement on two variables in scientific format.
e.g.

b=3.21e+02

Ok, almost there. The numbers in the third column are not what is needed.
It should be.
AA124 0.60273000 6.141498e+02
AA124 0.63239000 6.141498e-01
AA124 0.64585000 4.636831e+01
BB152 0.66250000...

Ok; but I get something different.
BB152 6.279650E+02
AA124 6.279650E+02
instead of
AA124 0.60273000 6.141498e+02
AA124 0.63239000 6.141498e-01
AA124 0.64585000 4.636831e+01
BB152...

I get nothing...

It does! file2 should be file1 though in your suggestion.
I wanted to remove the lines below a certain value of v
Thank you
