Find if a filename exists and act accordingly

[gvidos]

Hi,

I need to check if a file exists and only then execute it.

for example (in C format)
file="myfile"
if(file exists)
system("file&quot

Thanks

hi,

do you want this in shell script ?
if so ,

if [ -f /tmp/filename ]
then
print " it exists execute file "
/tmp/filename
else
print " not exist "
fi

Take a look at the man page for if, for other flags

man if

You may want to check on if the file in question has execute rights. You do that with the -x option:

#!/bin/sh

if [ -x $file ]
then
  print " $file exists - executing..."
  $file
else
  if [ -f $file ]
    print " $file exists - but I need to pass it to the shell to run..."
    /bin/sh $file
  fi
fi

Hope this helps. Einstein47
