$AfullnameLst is a list of file names passed to the script as command line arguments.

---------- Post updated at 11:14 AM ---------- Previous update was at 11:11 AM ----------

I have coded like this

Code:
foreach f ($AfullnameLst)
  echo "$f"
  ls $f
  if (-e $f) then
    echo "$f: file exists"
  endif
end

and I am getting

Code:
n02-z30-sr65-rgdt0p25.xt
-rw-rw-r-- 1 chrisd prog 4719 2010-11-09 17:44 n02-z30-sr65-rgdt0p25.xt
Bad : modifier in $ ( ).

So "ls" is picking up the file.

Have tried the below, using a variable does work but when I use foreach I am getting the problem. I have checked the file names in $AfullnameLst and they are correct. I just pass one file as a test.

Code:
if (-e "n02-z30-sr65-rgdt0p25.xt") then
  echo "file exists"
else
  echo "file does not exist"
endif

set myfile = "n02-z30-sr65-rgdt0p25.xt"
if (-e $myfile) then
  echo "file exists"
else
  echo "file does not exist"
endif

echo "Check if files exist"
foreach f ($AfullnameLst)
  echo ".$f."
  ls $f
  set file = "$f"
  if (-e $file) then
    echo "$f: file exists"
  endif
end
echo "Files checked"
