[SOLVED] Catch result of extract file of 7z

gajananh999 · 10-26-2012, 12:42 AM

Dear All,

I have written a batch file which do the extract .7z files from specific folder so i want to check weather file is successfully extracted or no

Here is my code

Code:

#!/bin/bash
FILES=/logs/isac/collation/data/server1/*.7z
for f in $FILES
do
  echo "Processing $f file..."
  # take action on each file. $f store current file name
   res=7za u -o/logs/isac/collation/data/logs2/ "$f"
   echo $res

done

Its giving error saying

./isacExtractor: line 7: u: command not found

This generates the error:

Code:

res=7za u -o/logs/isac/collation/data/logs2/ "$f"

If you want to store the output of a command in a variable you need to do this:

Code:

var="$(command)"

So the line in question should look like this:

Code:

res="$(7za u -o/logs/isac/collation/data/logs2/ "$f")"

Shouldn't that be echo $res

Code:

#!/bin/bash
FILES=/logs/isac/collation/data/server1/*.7z
for f in $FILES
do
  echo "Processing $f file..."
  # take action on each file. $f store current file name
   res="$(7za u -o/logs/isac/collation/data/logs2/ "$f")"
   echo $res

done

What is happening when you run the script? Do you get an error message, does it run without any message to screen, do you get the prompt back?

Also: Are you sure you want to use the u switch (which is for updating) and not the e switch (which is for extracting)?

Just do this:

Code:

if ! 7za u -o/logs/isac/collation/data/logs2/ "$f"
then
    echo "Extracting $f failed"
fi

Dear druuna,

I wont get any error massage but i get back to prompt

and u is use for extract and put the file in specified directory if already present also

and e is use to extract the files.

You can also make it more straightforward:

Code:

if 7za u -o/logs/isac/collation/data/logs2/ "$f"
then
    echo "Extracting $f successful"
else
    echo "Extracting $f failed"
fi
