Moving file using test command
My process creates file like

abc.20090427.txt i.e abc.date.txt

next time when my process it has to detect if any previous "abc" exist.
If exist then move to archive and create a new abc file.


I am using test command but it doesnt allow wild card.
Code:
if [[ -f abc.*.txt ]]
then 
mv abc.*.txt archive/abc.*.txt
fi

case statement will not work in this scenario since it cannot detect whether the file "abc" already exists.

Appreciate your help

That is not the test command; the test command is test or [.

Code:
is_file() { [ -f "$1" ]; }

if is_file abc.*.txt
then
  mv abc.*.txt archive/

In my directory i have
abc.txt
def.txt

Code:
#!/bin/ksh
is_file() { [ -f "$1" ]; }
if is_file *.txt
then
  mv *.txt archive
fi

when i run the above code the files are still there

What is the output of this script:

Code:
is_file() { [ -f "$1" ]; }

printf "%s\n" *.txt
if is_file *.txt
then
  mv *.txt archive
fi
printf "%s\n" *.txt


This version of is_file is a little more robust:

Code:
is_file() {
  for f; do
    [ -f "$f" ] && return
  done
  return 1
}

Tried both doesnt gives any output.

I have two files with .txt at ending but they are not moved

Code:
#!/bin/ksh
is_file() {
  for f; do
    [ -f "$1" ] && return
  done
  return 1
}
printf "%s\n" *.txt
if is_file *.txt
then
  mv *.txt archive
fi
printf "%s\n" *.txt

Code:
#!/bin/ksh
is_file() {
  for f; do
    [ -f "$f" ] && return
  done
  return 1
}
printf "%s\n" *.txt
if is_file *.txt
then
  mv *.txt archive
fi
printf "%s\n" *.txt

If there is no output, you don't have any *.txt files in the current directory.

Are you running the script in a different directory?

Script runs no output and files are not moved
