I have a problem where I get one behavior when I run a file from a cron and another when I run it from the command line. Attached is my cygcheck.out file. When I run the following script from the command line: ------------------------ $ cat testscript.scr mydir="/home/tompagano/test" cd $mydir rm sntl_data* wget -E --http-user=anonymous --http-passwd=tpagano@ ftp://ftp.wcc.nrcs.usda.gov/pub/outgoing/chris/snotel/sntl_data.csv <ftp://ftp.wcc.nrcs.usda.gov/pub/outgoing/chris/snotel/sntl_data.csv> chmod 777 $mydir/sntl_data.csv
cat $mydir/sntl_data.csv > $mydir/sntl_data_catted.csv cp $mydir/sntl_data.csv $mydir/sntl_data_copied.csv mv $mydir/sntl_data.csv $mydir/sntl_data_moved.csv cat $mydir/sntl_data_moved.csv > $mydir/sntl_data_moved_then_catted.csv head -10 $mydir/sntl_data_moved.csv > $mydir/sntl_data_moved_then_headed.csv awk 'NR <= 10' $mydir/sntl_data_moved.csv > $mydir/sntl_data_moved_then_awked.csv /////////////////////// I get output that looks just fine, as expected ----------------------- total 452K -rw-r--r-- 1 jim.marron None 22K Sep 9 11:51 cygcheck.out -rw-r--r-- 1 jim.marron None 103K Sep 9 13:09 sntl_data_catted.csv -rwxr-xr-x 1 jim.marron None 103K Sep 9 13:09 sntl_data_copied.csv* -rwxrwxrwx 1 jim.marron None 103K Sep 9 13:09 sntl_data_moved.csv* -rw-r--r-- 1 jim.marron None 1.6K Sep 9 13:09 sntl_data_moved_then_awked.csv -rw-r--r-- 1 jim.marron None 103K Sep 9 13:09 sntl_data_moved_then_catted.csv -rw-r--r-- 1 jim.marron None 1.6K Sep 9 13:09 sntl_data_moved_then_headed.csv -rwxrwxrwx 1 jim.marron None 664 Sep 9 13:09 testscript.scr* //////////////////////// Note the size of the files. I imagine everyone's familiar with awk, but the command is essentially the same as head -10, i.e. print out the first 10 lines. However, if I run this on a cron, like * * * * * /home/tompagano/test/testscript.scr > /tmp/cron.log I get the following output ------------------------ $ ls -l total 241K -rw-r--r-- 1 jim.marron None 22K Sep 9 11:51 cygcheck.out -rw-rw-rw- 1 jim.marron None 0 Sep 9 13:18 sntl_data_catted.csv -rwxrwxrwx 1 jim.marron None 103K Sep 9 13:18 sntl_data_copied.csv* -rwxrwxrwx 1 jim.marron None 103K Sep 9 13:18 sntl_data_moved.csv* -rw-rw-rw- 1 jim.marron None 1.6K Sep 9 13:18 sntl_data_moved_then_awked.csv -rw-rw-rw- 1 jim.marron None 0 Sep 9 13:18 sntl_data_moved_then_catted.csv -rw-rw-rw- 1 jim.marron None 59 Sep 9 13:18 sntl_data_moved_then_headed.csv -rwxrwxrwx 1 jim.marron None 664 Sep 9 13:09 testscript.scr* ///////////////////////// And sntl_data_moved_then_headed.csv contains: Cannot open file /home/tompagano/test/sntl_data_moved.csv This is a simplification of a much broader script I've been trying to run that was failing, but I've been able to isolate it down to this specific problem. I'm quite baffled as to why moving then awking a file would give a different result than catting or heading. It doesn't appear to be a permissions issue as far as I can tell because I can still move the files around? Am I missing something here? Thanks Tom
