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_number"p"' /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 $line_number"p" /tmp/results >"$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
