Java Validate file prefixed with characters
i have to check a file prefixed with ABC_, XYZ_ etc
For example : ABC_add
kindly give some ideas for validating the file prefixed with characters using SHELL script

i tried as follows but it is failing
Code:
f1='ABC_'
if [ ! -f $f1$file ]
then
echo "f1 passed";
fi

Hi.

Your code looks OK (for a single file) so long as $file is set.

What is failing?

for a single file its OK
i am checking multiple files.... i.e n number of times if is executed
Code:
f1='ABC_'
f2='XYZ_'
f3='DHF_'

if [ ! -f $f1$file ]
then
echo "f1 passed";
if [ ! -f $f1$file ]
then
echo "f1 passed";
if [ ! -f $f1$file ]
then
echo "f1 passed";
fi

always "f1 passed" message is displayed

Your script doesn't really work:

Code:
f1='ABC_'
f2='XYZ_'
f3='DHF_'

if [ ! -f $f1$file ]
then
echo "f1 passed";
fi

if [ ! -f $f2$file ]
then
echo "f2 passed";
fi

if [ ! -f $f3$file ]
then
echo "f3 passed";
fi

What is the value of the file variable?

Java
file will be holding static value....
for example ABC_file1

Hi.

I cannot see a problem now...

A quick test:
Code:
$ cat fileTest
f1='ABC_'
f2='XYZ_'
f3='DHF_'

file=file1
touch $f1$file

if [ ! -f $f1$file ]
then
echo "f1 passed";
fi

if [ ! -f $f2$file ]
then
echo "f2 passed";
fi

if [ ! -f $f3$file ]
then
echo "f3 passed";
fi


$ ./fileTest
f2 passed
f3 passed

Perhaps the files are located somewhere else? Not in the directory you run the script from.
