hey guys, I've written this script to read a file from a cd and if the cd file isn't present, I want it to check the floppy drive for that same file, if the floppy drive does not have it I want to return a statement saying no disk found. It also copies files and so forth if the files are available but that stuff is working fine, its the actual if then statements that don't cycle right. Here is my code so far but when I put whitespace between "if" and "[" if gives me the "missing ]" error which does away if I delete the spaces. however when i get it running correctly It does every sequence of steps in order instead of following my if then commands. for example, I will put my output under the code.
Code:
#!/bin/sh
cd /ANIMALS
cp -r TIGERS TIGERS_QA
chmod 777 TIGERS_QA
echo ======Finished backing up files======
#******************************************************************************
# Determine whether a CD or floppy disk was inserted, then proceed to
# according tasks
#
# ***CD VERSION***
# Copy .tgz file from cd to hard drive and extract folder to replace
# current files.
#******************************************************************************
cd ..
if [ -f cdrom/TIGERS.tgz ]
then
cp -r cdrom/TIGERS.tgz ANIMALS/TIGERS.tgz
cd ANIMALS
tar xvf TIGERS.tgz
chmod 777 TIGERS.tgz
echo ======Finished searching for cd======
#******************************************************************************
# ***FLOPPY VERSION***
# Copy .tgz file from floppy disk to hard drive and extract folder to
# replace current files.
#******************************************************************************
cd ..
elif [ -f dev/TIGERS.tgz ]
then
cp -r dev/TIGERS.tgz ANIMALS/TIGERS.tgz
cd ANIMALS
tar xvf TIGERS.tgz
chmod 777 TIGERS.tgz
echo ======Finished searching for floppy disk files======
else
echo ======Insert CD or Floppy Disk======
fi
OUTPUT(with white spaces removed after if):
Code:
Install_Tigers
cp: cannot access TIGERS
chmod: WARNING: can't access TIGERS_QA
======Finished backing up files======
if[-f: No match
then: Command not found
tar: blocksize = 0
======Finished searching for cd======
elif[-f: No match
then: Command not found
tar: blocksize = 0
======Finished searching for floppy disk files======
else: endif not found
If I replace fi with endif I get the final statement also which says
======Insert CD or Floppy Disk======
However I only want this statement if the file cannot be found in the cd or floppy drives. which is not what it does, it shows it everytime.

Reason: adding code tags
#!/bin/sh
SRC=""
cd ..
if [[ -f cdrom/TIGERS.tgz ]] ; then
SRC=cdrom/TIGERS.tgz

if [[ -f dev/TIGERS.tgz && -z "$SRC" ]] ; then

if [[ -z "$SRC" ]] ; then
echo "file not found"
exit 1

cp "$SRC" ANIMALS/TIGERS.tgz
cd ANIMALS
tar xvf TIGERS.tgz
chmod 777 TIGERS.tgz
echo "done"
exit 0

Resolved by changing the first line to bash rather than csh, does bash and csh treat the brackets differently?
