How to check for a file? 1

[jpor]

Hello Again,

I am wondering if anyone could enlighten me in how I can find out if a file is present within a Korn Shell script?

At the moment I am depending on a remote site to ftp a file over for which then I have a ksh which checks for things like '0' bytes, commas and changing lowercase characters to uppercase etc.. All I need to to is make usre the file is actually available before doing any of this.

The KSH is running on AIX ver 4.3.3 ML9.

Thanks in advance.

Method 1

if [ -f filename ]
then
  echo filename exists
fi

Method 2

[[ -f filename ]] && echo filename exists

checks for things like '0' bytes
[ -s /path/to/file ] || echo "empty or unreachable"

Hope This Helps, PH.
