UNIX for Dummies Questions & Answers

I would... because if the script is in your PATH, it cane be executed anywhere...
So for safety:

Code:

#!/bin/bash
# Running through Fortran Program used to find anomaly of Rain and Temperature

#FILES="/Users/jduncan/Desktop/rawdata/"

cd <to where the *.txt are>


for File in *.txt
do
     ./runthrough.o "$File" 

done

This ./runthrough.o is where?

Second thought: Since I dont know what ./runthrough.o does:
Try to see if loop is working:

Code:

#!/bin/bash
# Running through Fortran Program used to find anomaly of Rain and Temperature

#FILES="/Users/jduncan/Desktop/rawdata/"

for File in *.txt
do
     # ./runthrough.o "$File"  comment out for the test: If test works,the culprit is here somewhere...
   ls -l $FILE

done

Code:

OPEN(10,file='"$File"',status='old')

FORTRAN is not shell. "$File" doesn't work here.

You can get variables you've exported with GETENV, or things you've fed it on the commandline with GETARG, but we don't seem to be FORTRAN experts, ergo it would really be much simpler to just follow the suggestion I gave you days ago: Don't bother opening any files inside FORTRAN at all. Read from standard input, write to standard output. This is often how UNIX utilities are supposed to work anyway -- makes things easier to put in a pipe chain.

'standard input' and 'standard output' amount to pre-opened file numbers, stdin being either 5 in F77 or 100 in F95, and stdout being 6 in F77 or 101 in F95 (according to According to this). Reviewing the thread, I see this was even linked earlier.

When you don't redirect them, they inherit it from whatever it's being run from -- in a terminal, it would get your keyboard as stdin and your screen as stdout. But you can send them anywhere you want with the shell:

Code:

./myprogram < inputfile > outputfile

So if myprogram was an F77 program, writing to 6 would write to outputfile and reading from 5 would read from inputfile...

Thanks for your Enlightenment Corona688 !

Thanks, I was confused earlier with the 'standard input/output' because I always though you had to have a file name no matter what unit identifier you used. That's where the confusion was.

I'm still having one small problem but I'll play around with it and see what happens...But I am making progress!!!

I think FORTRAN predates the concept of "file", so...
