Scrutinizer is quite correct. The filename expansion is taking place first and creating a long [ -e ] statement.
On my tests, a "test -f" is only actually testing the first name in the expanded list! If we seed the test with discrete filenames we get some unusual behavior:
Therefore those methods which either count the number of files or process each file in a loop are preferable. If nothing else because some implementations of "ksh" don't seem to cope with the expanded list.
Footnote: ksh88 is definitely not Posix compliant. Many standards have come and gone (including past failed Posix standards) since ksh88 was released. I find ksh88 to be pretty standard across multiple platforms of multiple vintages and continue to wait for a viable replacement cross-platform standard.
I'm sure this can't be too tough, but.
I want to check the existance of file(s) by extension. There may be 0,1,N files. If any files exist, then remove them.
Thanks for any insight. (3 Replies)

echo
echo(1B) SunOS/BSD Compatibility Package Commands echo(1B)NAME
echo - echo arguments to standard output
SYNOPSIS
/usr/ucb/echo [-n] [argument]
DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output.
echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi-
ronment variables.
For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows:
o echo your current-working-directory's full pathname
o pipe the output through tr to translate the path's embedded slash-characters into space-characters
o pipe that output through wc -w for a count of the names in your path.
example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w"
See tr(1) and wc(1) for their functionality.
The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if
the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape
characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's
echo() also understands a as the audible bell character; however, these commands do not have an -n option.
OPTIONS -n Do not add the NEWLINE to the output.
