I am attempting to error check so that if the file is not an ordinary file it will echo File is not an ordinary file.
#!/bin/csh
echo Enter file name
set filename = $<
if(-f $filename)then
if(-z $filename)then
rm $filename
else
clear
echo $filename
du -sh $filename
stat -c %h $filename
stat -c %U $filename
date -r $filename
endif
else
echo File is not an ordinary file
endif
when I run this with for example fake.txt it comes up with
du: cannot access fake.txt': No such file or directory stat: cannot stat
fake.txt': No such file or directory stat: cannot stat `fake.txt': No such file or directory date: fake.txt: No such file or directory
what am I missing?
REDO:
#!/bin/csh
echo Enter file name
set filename = $<
endif
test -f $filename
if ( $status == 0 ) then
if(-z $filename)then
rm $filename
else
clear
echo $filename
du -sh $filename
stat -c %h $filename
stat -c %U $filenam
endif
else
echo "File is not an ordinary file."
endif
There is a much easier way to determine if a file is a regular file (and exists):
#!/bin/csh
echo "Enter filename: "
set filename = $<
test -f $filename
if ( $status == 0 ) then
echo "File is an ordinary file."
else
echo "File is not an ordinary file."
endif
# end of file.
Details on how test(1) works can be found from an appropriate manual page. In this example I've simply used the fact that test(1) exits with a non-zero exit code in case the test condition used is not fulfilled: switch -f tests that the argument given exists and is a regular file.
