I am very new to bash scripting and this is my first script.
I am trying to write a script that takes an argument d as the directory.
It looks through the files to find duplicates and delete them.
Here's some sorta-pseudocode but am unsure how to implement it:
Code:
#! /bin/bash
#get directory contents
for file1 in $1
for file2 in $1
if [ -f file1 && -f file2 ] then
if [ cmp file1 file2 ] then
#delete accordingly
#create hard link
fi

I can't seem to understand how i can translate that... (5 Replies)

num1=$(( $RANDOM % 10 ))
num2=$num1

num2=$(( $RANDOM % 10 ))

KSH isn't my strong suit but it's what my company has to offer. I've got a script with two nested loops, a FOR and UNTIL, and that works fine. When I add a CASE into the mix I end up getting "Unexpected 'done' at line xx" errors. Any suggestions on this?

xzdiff
XZDIFF(1) XZ Utils XZDIFF(1)NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files
SYNOPSIS
xzcmp [cmp_options] file1 [file2]
xzdiff [diff_options] file1 [file2]
lzcmp [cmp_options] file1 [file2]
lzdiff [diff_options] file1 [file2]
DESCRIPTION
xzcmp and xzdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), bzip2(1), or lzop(1). All options specified
are passed directly to cmp(1) or diff(1). If only one file is specified, then the files compared are file1 (which must have a suffix of a
supported compression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they
are uncompressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp(1) or diff(1) is preserved.
The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.
SEE ALSO cmp(1), diff(1), xz(1), gzip(1), bzip2(1), lzop(1), zdiff(1)BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
