Question help- wildcard not working in shell
hi,
i need to check the existence of all files starting with abc in a directory. The code works fine with a particular file name, but the file existence is not detected when i use wildcard character (abc*)

kindly suggest what could be the issue Smilie


Code:
src_filename1=$AI_LANDING/abc*
printf "Checking for file \n $src_filename1 ...."
if [[ ! -s $src_filename1 ]]
then
print -u2 "ERROR: File was not found"
print -u2 "FILENAME: $src_filename1"
print -u2 ""
else
print " $src_filename1 EXISTS!!"
fi

For testing purpose there is only one file present in the directory whose name starts with abc.

Can you check once with set -x option enabled and paste the output?

It always helps to know what Shell you have.

One unrefinded idea which should still work whether or not the file exists. Of couse if the file does not exist, ${src_filename} is blank.

Code:
src_filename1=`ls -1d abc* 2>/dev/null|tail -1`
printf "Checking for file ${src_filename1} ...."
if [ ! -s "${src_filename1}" ]
then
    print -u2 "ERROR: File was not found"
    print -u2 "FILENAME: ${src_filename1}"
    print -u2 ""
else
    print " ${src_filename1} EXISTS!!"
fi

Thanks for your response. I am using ksh

I tried the following code like you have suggested
Code:
src_filename1=$AI_LANDING/`ls -1d abc* 2>/dev/null|tail -1`
printf "Checking for file ${src_filename1} ...."
if [ ! -s "${src_filename1}" ]
then
    print -u2 "ERROR: File was not found"
    print -u2 "FILENAME: ${src_filename1}"
    print -u2 ""
else
    print " ${src_filename1} EXISTS!!"
fi

This is evaluating the src_filename1 as only the AI_LANDING path without the file name, and giving the result as EXISTS! even when the file is not present.

Any suggestions?

try this
Code:
#!/bin/ksh
AI_LANDING=/searchdir
ls -1 ${AI_LANDING}/abc*|while read -r src_filename1 ; do
print "Checking for file $src_filename1 ...."
if [[ ! -s $src_filename1 ]]
then
print -u2 "ERROR: File '$src_filename1' was not found or has not a size greater than zero"
print -u2 ""
else
print "$src_filename1 EXISTS!!"
print -u2 ""
fi
done

If it evaluates src_filename1 as the path, then it does exist -- it's the directory $AI_LANDING. And it's not empty, so the test passes. All kosher there.

As for your original problem, I'd put it in a for loop:
Code:
for src_filename1 in $AI_LANDING/abc* ; do 
  whatEvahYouNeed2DoWith $src_filename1
done

Reading through your original post I have to ask:
Quote:

Is this "testing - purposes" file named abc<somethin> empty by any chance? Because then it wouldn't pass your test...
When you want to test for existence, use
Code:
if [ -f $file ] ; then

test instead. -f returns true if the file exists and is a regular file (as opposed to a directory, block or special device, etc.)

Hi,

I tried the above code but it is still not finding the file at the directory..This is the output I get

* Unix file permissions may prevent an accurate summation of reported data.
/abc*: No such file or directory
