Routine doesn't give output when executed in crontab
I have a script running in the crontab that gets data from a database every hour. Now I would like to execute a fortran routine to process the data in some way, after getting it and saving it locally.

I have added the following commands to my script:

set convert = ${outputdir}/Scripts/data_latest.txt

cd ${outputdir}/Scripts
f90 -o routine.x routine.f
routine.x filename.dat > $convert

The output from the routine should be written in the 'convert' file, which is data_latest.txt. The file 'filename.dat' is the input file which was received from the database. When I run the script separately, the 'convert' file is filled with output, but when the script is executed in the crontab, it is completely empty.

What should I do in order to run this routine (embedded in the script) automatically and receive my output in the output file?

Thanks in advance.

Users who desire to have their .profile executed must explicitly do so in the crontab entry. Why?

The .profile file should be read when the user logs in. So, there should be no need to execute .profile file again in a cron job (since the cron job is run after the user logs in). Doesn't the cron require login from the user. Then, from where does the cron execute? Please help!! (1 Reply)

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
