UNIX for Dummies Questions & Answers

before i get to it, i would like to say this is the greatest unix site ive ever seen, and im glad to see so many people are out there to help. thanks

well, im trying to make myself a script where i can specify a directory and a file size so that my script will show me any files larger than the size i specify.

im using the find command, like so:

find $1 -type f -size +$2k -print

i know its not right because ive already run it and recieved errors and i pretty much modified that line from the find man page. any help or pointers would be appreciated

thanks

Assuming GNU find (given your nick):

Code:

show_bigger(){ find -type f -size +"$1" -ls 2>/dev/null;}

For example:

Code:

% show_bigger 10M
1550976 66296 -rw-r--r--   1 root     root     67810654 Sep  9 20:25 ./sqldeveloper_1.5.54.40-2_all.deb
1550982 66308 -rw-r--r--   1 radoulov radoulov 67825452 Sep  9 20:24 ./sqldeveloper-1.5.54.40-1.noarch.rpm
819309 27012 -rw-r--r--   1 radoulov radoulov 27624080 Oct 16 11:58 ./fuz2y_desktop_theme_v1.2.tar.gz

Just saw you want to pass the path too, so:

Code:

show_bigger(){ find "$1" -type f -size +"$2" -ls 2>/dev/null;}

In zsh you could use (size is in bytes):

Code:

print -rl -- **/*(.DL+10000000)

Let me try to separate each command for you

find $1 -type f -size +$2k -print

at this line $1 and $2 work as a parsing variable that usually work when you make application and run it from unix using ./(app_name) (parameter).

find $1 : you must fill $1 with path, exp: /user or . (for current dir) or /home
-type f : means the type that your looking was a file
-size +$2k :fill $2 with number exp: 1,2,3 that remark size of file your looking for +2K means search for file bigger than 2 KB
-print : show the result on the screen

good luck, keep on UNIX

thanks guys, im gunna give it a shot n see how it goes

actually i have a question, the 2>/dev/null; is that for error redirection?

Yes.
