Full Discussion: check the directory exist
Top Forums Shell Programming and Scripting check the directory exist Post 77097 by mbb on Monday 4th of July 2005 09:59:17 AM

FYI ust:

if [ -d $dir ]
then
...
fi

is actually using the 'test' command. To find out what you can do with the test command then type: 'man test'

You may also write the above as:

if test -d $dir
then
...
fi

or even use the test command on the comand line thus:

>test -d $dir
>echo $?

Also I would recommend shell variables to be quoted in this context:

if [ -d "$dir" ] ...

to avoid any command line errors with the test command!

i.e. if $dir were emtpy and you did if [ -d $dir ], then you would really be running: 'test -d' and the test command would complain.

Hope this helps.

NAME
perluts - Perl under UTS SYNOPSIS
This document can be read as is: as README.uts, or you can read it after you build your package using "man perluts". The purpose is to help you build Perl for UTS, which, if you follow these instructions, should be easy, and result in a solidly working installation. DESCRIPTION
Perl 5.7.2 (Developmental) or Perl 5.8.x (forthcoming) for UTS BUILDING PERL ON UTS
NOTE: Some sites have redefined the way uname works, and if yours does this, special steps must be taken so that Configure can recognize your system as a UTS system. To see if you are in this category, issue the command "uname -a". It should look something like: uts juno 4 4.4 9672 370 At any rate, the first field should be "uts". If this is not the case; supposing it is, say telcoUTS, create a script, uts/uname (i.e. uname, in the subdirectory "uts" of the main Perl source dir): # uname /usr/bin/uname "$@" | sed -e 's/^telcoUTS/uts/' and when you execute Configure, do it as below, except for adding PATH=uts:$PATH as a prefix. I.e. do: PATH=uts:$PATH ./Configure ... There is no need to do an interactive configure, just type ./Configure -de [-Dusedevel] [-Doptimize=-g ] 2>&1 | tee Conf.out "-Dusedevel" may be required to configure Perl 5.7.2 non-interactively. Use -Doptimize=-g if you want to run Perl under sdb or gdb, OR if you want to be able to use the -D command line flags to perl, which are occasionally useful in debugging perl scripts. In this and the following steps, the "2>&1 | tee XXX.out" records all output from the process, which will be useful if anything unexpected goes wrong. Then do the compilation with make 2>&1 | tee make.out Finally, test using make test 2>&1 | tee make-test.out In the output, the only failures you should see should look like: lib/Math/BigInt/t/bigfltpm.........Use of uninitialized value ... FAILED at test 57 lib/Math/BigInt/t/bigintc..........ok lib/Math/BigInt/t/bigintpm.........FAILED at test 204 lib/Math/BigInt/t/mbimbf...........Use of uninitialized value ... Illegal division by zero at ../lib/Math/BigInt/Calc.pm line 314. FAILED at test 71 lib/Math/Complex...................exp: OVERFLOW FAILED at test 250 lib/Math/Trig......................exp: OVERFLOW ok lib/Memoize/t/array................ok ... lib/Net/protoent...................ok lib/Net/servent....................FAILED at test 0 This means that everything passes except for some problems in the packages "Math::BigInt", "Math::Complex", and "Math::Trig". The lib/Net/servent failure seems to be a bug in the test program. To confirm this, from the main Perl source dir, do: LD_LIBRARY_PATH=`pwd` ./perl -Ilib lib/Net/servent.t and it should output 1..3 ok 1 ok 2 ok 3 Installing the built perl on UTS Run the command "make install" AUTHOR
