Re: Quotes problem ?
Hello , Eric: Sorry, I forgot to mention the platform. It is a Sun 250 with Solaris 8.Thank you anyway. Paul: It worked with the changes you told me. Thank you very much.I still have a question anyway: You said that line cd $path should be better with quotes to avoid problems with dir names containing spaces, so did you mean this? cd $path -- View this message in context: http://www.nabble.com/Quotes-problem---tf2952284.html#a8275269 Sent from the Gnu - Bash mailing list archive at Nabble.com. ___ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash

Quotes problem ?
Hello ,
I'm having problems with the script I send below.
Problem description:
I'm trying to run a script called logo_changer.sh that creates a file called
results containing different lines
and every line is a path to a dir where the logo_1.gif file is located.
After the
results file is filled, I try to read it line by line, go to every dir
refered in that line,
check the size of the logo_1.gif file in that dir and then store both path
and size of every
logo_1.gif file founded on the system in a file called report.
I run bash -x logo_changer.gif and the result is this:
...
[cut some lines here with same message]
...
+ sed -n '$line_numberp' /tmp/results
/tmp/logo_changer.sh: : No such file or directory
+ cd
+ pwd
+ ls -go logo_1.gif
logo_1.gif: No such file or directory
+ awk '{print $3}' /tmp/size
+ echo
+ line_number=line_number+1
+ i=6
+ '[' 6 -le 5 ']'
can anybody reproduce the problem and tell me what is wrong?
#!/usr/local/bin/bash
#Execute it from /ecas
#We search for the string logo_1.gif and store the resulting paths in
results_1
find . -name logo_1.gif /tmp/results_1
#Delete logo_1.gif string from every line in results_1,
#leaving only the path to prepare for cd step
sed 's/logo_1.gif//' /tmp/results_1 /tmp/results
#Initialization of variables
i=1
line_number=1 #every line (dir path) stored in results
path=
while [ $i -le 5 ]#In fact it contains more than 5 of course...
do
#Start taking line by line and store it the path variable
sed -n $line_numberp /tmp/results $path
#We change to dir stored in the path variable
cd $path
#Print actual path into /tmp/report to check later
pwd /tmp/report
#Take the size of logo_1.gif file from current dir
ls -go logo_1.gif /tmp/size
#Print actual file size into /tmp/report to check later
awk '{print $3}' /tmp/size /tmp/report
#Print a blank line at the report after every path and size to see things
clearer
echo /tmp/report
#Update variables
line_number=line_number+1
i=$[$i+1]
done

However, my guess would be that you are on cygwin, and that your script has CRLF line endings even though you told cygwin to respect CR as a literal character rather than ignoring it (because you used a binary instead of a text mount). The output messages resemble a rash of similar messages reported to the cygwin list for the same root cause. If my ESP is strong enough to have correctly diagnosed your problem, then the fix is simple - remove the CR from your script by running d2u on it. - -- Don't work too hard, make some time for fun as well!

It redirects the output of a command to a file. If you want to store the output in a shell variable, use this: path=$(sed -n $line_numberp /tmp/results) #We change to dir stored in the path variable cd $path Quotes would be useful here, in case you have a directory name containing spaces. paul ___ Bug-bash mailing list Bug-bash@gnu.org http://lists.gnu.org/mailman/listinfo/bug-bash
