Sesuai judul ane mau nanya nee gan...
ane kan punya kodingan bash skrip

#!/bin/bash



for output in $(find . -name "*.pdf")

do

a=`pdfgrep -in yourstring $output`

echo $a

done

Hasilnya malah

pdfgrep: could not open ./some

pdfgrep: could not open thing

pdfgrep: could not open in.pdf

padahal direktori /home/<user>/files ane ada file
some thing in.pdf

kalau spasinya di ganti underscore lancar gan.
kira kira gimana ya nghandle filename yang berisi spasi di bash script.
