An easy one...

Please tell me what I'm doing wrong!!!



i=79 \
j=1 \
while [ $i -gt 0 ] \
do \
j =`expr $i + 1` \
if [ -d $SNAPSHOT_RW/hourly.$i ] ; then \
$MV $SNAPSHOT_RW/hourly.$i $SNAPSHOT_RW/hourly.$j ; \
fi; \
i=`expr $i - 1` \

done \


I get
line 63: syntax error near unexpected token `then'
line 63: ` if [ -d $SNAPSHOT_RW/hourly.$i ] ; then \'



It should be an easy one! Thanks from a beginner scripter (not even close to a programmer!)

I'm trying to create a loop to do this from 79 to 1

if [ -d $SNAPSHOT_RW/home/hourly.2 ] ; then \
$MV $SNAPSHOT_RW/home/hourly.2 $SNAPSHOT_RW/home/hourly.3 ; \
fi;
if [ -d $SNAPSHOT_RW/home/hourly.1 ] ; then \
$MV $SNAPSHOT_RW/home/hourly.1 $SNAPSHOT_RW/home/hourly.2 ; \
fi;

Well, with the code you posted the space between "j" and "=" in the line
j =`expr $i + 1` is a bit of a problem :)

Is there a reason you're using expr to evaluate the math? It's simpler to use bash's internal math routine:

j=$((i + 1))

Hmm thanks. I fixed that but still get the error:

line 65: syntax error near unexpected token `then'
line 65: ` if [ -d $SNAPSHOT_RW/hourly.$i ] ; then

I have no clue. I pasted your code into a file, and tested it, and that space was the only error I got.

Here's the code I was testing (I removed some redundant semicolons as well as spaces, and formatted it so that it's more readable):

#!/bin/bash

i=79
j=1
while [ $i -gt 0 ]; do
j=$((i + 1))
if [ -d $SNAPSHOT_RW/hourly.$i ]; then
$MV $SNAPSHOT_RW/hourly.$i $SNAPSHOT_RW/hourly.$j
fi
i=$((i - 1))
done

Okay, I tested it as a single-line command (without the line continuation characters). What was causing the error was the lack of a semicolon on the "j=`expr $i + 1`" line. Here's the line I was testing:
i=79; j=1; while [ $i -gt 0 ]; do j=`expr $i + 1`; if [ -d $SNAPSHOT_RW/hourly.$i ]; then $MV $SNAPSHOT_RW/hourly.$i $SNAPSHOT_RW/hourly.$j; fi; i=`expr $i - 1`; done;
