Linux Shell Script to unzip and split file outputs unreadable files -

i have zip folder contains multiple files of same format. each file around 50 mb size. need split each file multiple chuncks (say 1000 lines per spllited output file).

i have written shell script which unzips folder , saves split files output in directory.

the problem output chunks in unreadable format containing symbols , random characters. when each file individually, outputs perfect txt split files. not happening whole zip folder.

anyone knows how can files in txt format. here script.

for z in input.zip ;     if unzip -p "$z" | split -l 1000 $z output_dir ;     echo "$z" fi done 

problem

you need unzip files first. otherwise, chunking original binary zip file.

solution

the following untested because don't have source file. however, should work little tweaking.

unzip -d /tmp/unzipped input.zip mkdir /tmp/split_files  file in /tmp/unzipped/*txt do;     split -l 1000 "$file" "/tmp/split_files/$(basename "$file" .txt)" done
