Shell Programming and Scripting

Hello,

I have a script that "validates" a ZIP file that look like this

Code:

AAA_20120801.zip =>
x~back end~20120801.TXT
y~time in~20120801.TXT
z~heat_chamber~20120801.TXT
AAA_20120801.ctl

My task is to compare its contents (i.e the list of files contained inside) with the control file that is provided inside the ZIP file itself.

Since we've started receiving files with spaces in their name, I prevented the OS from word splitting file names when I view the ZIP's contents like so

Code:

FIRST_Array=(); while read length date time filename; do FIRST_Array+=( "$filename" ); echo -e "$filename"; 
done < <(/usr/bin/unzip -qql AAA_20120801.zip)

When I try to do the same with the control file,

Code:

SECOND_Array=(); while read filename; do SECOND_Array+=( "$filename" ); echo -e "$filename"; done < <(/usr/bin/unzip -p AAA_20120801.zip AAA_20120801.ctl )

SECOND_Array() correctly outputs the file names in the control files but it also output the file sizes listed in the control file

Code:

x~back end~20120801.TXT 2KB
y~time in~20120801.TXT 2KB
z~heat_chamber~20120801.TXT 2KB

and my array comparison (diff -q) fails.

I tried adding this bit of Awk() code to remove the file size field but it brings word splitting back!

Code:

SECOND_Array=(); while read filename; do SECOND_Array+=( "$filename" ); echo -e "$filename"; done < <(/usr/bin/unzip -p AAA_20120801.zip AAA_20120801.ctl |awk '{print $1}')

How can I remove the file size info and prevent word splitting? Any ideas?

Thank you.

Code:

while read -r line; do
  file=${line% *}
  size=${line##* }
  array+=( "$file" )
  printf '%s' "$file"
  ...
done

PS. Next you may get files with \ in them. use read -r and printf '%s\n' "$filename" instead of echo -e

This did the trick:

Thanks for taking the time.
