use the "test" command with the "-f" option. It tests for the existence of a (regular) file. You could even refine your test with the "-r" option, which tests for a regular file which has read access:
Code:
if [ -f /path/to/file ] ; then
print - "file /path/to/file exists and is a regular file"
else
print "file /path/to/file does not exist or is no regular file"
fi
if [ -r /path/to/file ] ; then
print - "file /path/to/file exists and is a readable regular file"
else
print "file /path/to/file does not exist or is not readable or no regular file"
fi
Employing the logic you use it would be possible to set a flag:
Code:
#! /bin/ksh
typeset -i lFoundSO=0
typeset fDir="/some/where"
typeset fFileBuffer=""
ls $fDir/SALESORDER*.dat | while read fFileBuffer ; do
lFoundSO=1
do_some_processing $fFileBuffer
done
if [ $lFoundSO eq 1 ] ; then
ls $fDir/PURCHASEORDER*.dat | while read fFileBuffer ; do
do_some_other_processing $fFileBuffer
done
fi
if [ $lFoundSO eq 0 ] ; then
print -u2 "Error: no SALESORDER-file found"
exit 1
fi
exit 0
Notice that i have not used a for-loop but a while-loop instead. The reason is that the commandline has a limited length (4096 characters per POSIX 1003). As the wildcards get expanded when processing the commandline it can well be that many matching files would make a string too long for the shell to digest. You would get a "line too long-error". Therefore the while-loop and a pipeline is more safe than the for-loop.
