Searching for a string on multiple zip files
I am working on SunOS 5.10. I have a folder that contains about 200 zip files. Each zip file contains only one text file in it. I would like to search for a specific string in all the text files in all the zip files.
I tried this (which searches for any text file in the zip file that contains the string "ORA-") but it didn't work.
zipgrep ORA-1680 *.zip
What is the correct of doing it without uncompressing the zip files?
See also How do I recursively grep through compressed archives? (not an exact duplicate, because the requirements there were more complicated).
It is in general not possible to search for content within a compressed file without uncompressing it one way or another. Since zipgrep is only a shellscript, wrapping unzip and egrep itself, you might just as well do it manually:
for file in *.zip; do unzip -c "$file" | grep "ORA-1680"; done
If you need just the list of matching zip files, you can use something like:
for file in *.zip; do if ( unzip -c "$file" | grep -q "ORA-1680"); then echo "$file" fi done
This way you are only decompressing to stdout (ie. to memory) instead of decompressing the files to disk. You can of course try to just
grep -athe zip files but depending on the content of the file and your pattern, you might get false positives and/or false negatives.
`unzip -c` decompresses the file to stdout. It doesn't write the whole uncompressed file anywhere else.
+1 tks a lot it save my day . I juste add echo "$file"; unzip -c "$file" | grep -q "ORA-1680"; to know the file name + the result.
