That's because this is not a cygwin specific problem. Try to find a
standard book about shell programming.
The "if" problem:
"if, elif" needs a "then"
if condition ; then
do_something
elif other_condition ; then
do_other_things
fi
You may place "then" on a seperate line:
if condition
then
do_something
fi
A special trap with "["
if [ $i -gt 5 ] ; then
# ^ this blank is a must
reason: "[" is an alias name for the command "test", the above really
means:
if test $i -gt 5 ; then
...
fi
do a "man test" to find the differences between "-gt" and ">" etc.

the cygwin manpage of "test" doesn't say anything about the difference between
this.

The Advanced Bash Scripting HOWTO is an excellent document for getting to
grips with that kind of issue:

Also you must include white space between the [ and the items under
test.
correct:
if [ $one -eq 1 ];then
incorrect:
if [$one -eq 1];then

* "if" "then" "elif" "fi" "done"

From: Harter, Pete @ 2001-09-05 23:01 UTC (permalink / raw)

Dear Cygwin:
I'm using Cygwin on NT, writing a bash script to catenate 241 files
together. I can't seem to get the "elif" "fi" "done" statements to work.
Using "then" seem to have no effect.
In particular, "elif","fi","done" all cause syntax errors. I've done a "man
bash", which tells me that the "fi", "elif", "done", etc. ought to work. I
can't find much on the www.cygwin.com about syntax.
Here's my commands:
#!/bin/bash -x
pdt="/cygdrive/e/temps"
pcase="case2"
#
cat $pdt/$pcase/$pcase'001'.bdf > $pdt/$pcase.temp
pi=2
while [$pi < 241]
do
if [$pi < 10]
cat $pdt/$pcase/$pcase'00'$pi.bdf >> $pdt/$pcase.temp
elif
if [$pi < 100]
cat $pdt/$pcase/$pcase'0'$pi.bdf >> $pdt/$pcase.temp
elif [$pi >= 100]
cat $pdt/$pcase/$pcase$pi.bdf >> $pdt/$pcase.temp
fi
fi
echo $pi
pi=$pi+1
done
I revised the commands (by trial & error) to the following, which gives no
syntax error except that it says "unexpected end of file" after the last
line:
#!/bin/bash -x
pdt="/cygdrive/e/temps"
pcase="case2"
#
cat $pdt/$pcase/$pcase'001'.bdf > $pdt/$pcase.temp
pi=2
while [$pi < 241]
do
if [$pi < 10]
cat $pdt/$pcase/$pcase'00'$pi.bdf >> $pdt/$pcase.temp
ei
if [$pi < 100]
cat $pdt/$pcase/$pcase'0'$pi.bdf >> $pdt/$pcase.temp
ei [$pi >= 100]
cat $pdt/$pcase/$pcase$pi.bdf >> $pdt/$pcase.temp
endif
endif
echo $pi
pi=$pi+1
enddo
Please help. Thanks
