Various kinds of loop on files in directory
for file in <directory>/*
do
echo $file
mv -f $file <another dir>
done
The is a problem with this for loop : if the directory is empty body of the loop is executed nevertheless with the variable file set to ‚<directory>/*‘
Another solution with the for loop :
Code:
for file in `ls -1 <directory>/* 2>/dev/null‘
do
echo $file
mv -f $file <another dir>
done
You can also use a while loop :
Code:
ls -1 <directory>/* 2>/dev/null |
while read file
echo $file
mv -f $file <another dir>
done

WGET
skus cez wget, do shellu hod: wget –save-cookies=./kolace "https://ssl.rapidshare.com/cgi-bin/premiumzone.cgi" -O /dev/null
–post-data="login=krasko&password=123456" so svojim loginom a heslom.
Nasledne sa ti vytvori subor kolace, potom si sprav subor zoznam do ktoreho si nakoporuj linky a spustis to takto: wget –load-cookies=./kolace -c -i zoznam .
A tot vse 😉
ja pouzivam command-line ‚wget‘, ten vie so spravnymi prepinacmi spravit jednoducho pekny komplet mirror webstranky.
wget -m -l 1 -k -c "http://stranka"
-m : mirror (shortcut for -N -r -l inf –no-remove-listing.)
-l : max depth level 1
-k : convert links to local
-c : continue if you broken download
