Sort by time and Reverse to get Ascending order, then display a marker next to the a file, negate directory and select only 1 result
Find which directories on your system contain a lot of files.
Edit: much shorter and betterer with -n switch.
This command will give you the same list of files as "find /etc/ -name '*killall' | xargs ls -l".
In a simpler format just do 'ls /etc/**/file'.
It uses shell globbing, so it will also work with other commands, like "cp /etc/**/sshd sshd_backup".
-sl : show just file names
Find all files in /var/spool/mqueue older than 7 days, pass to perl to efficiently delete them (faster than xargs or -exec when you've got millions or hundreds of thousands to delete). Naturally the type, directory, and file age vars can be adjusted to meet your specific needs.
Videos are found using their MIME type. Thus no need to for an extension for the video file.
This is a efficent version of "jnash" cmd (4086). Thanks for jnash. This cmd will only show video files while his cmd show files having "video" anywhere in path.
Change "sort -f" to "sort" and "uniq -ic" to "uniq -c" to make it case sensitive.
Tells you everything you could ever want to know about all files and subdirectories. Great for package creators. Totally secure too.
On my Slackware box, this gets set upon login:
LS_OPTIONS='-F -b -T 0 --color=auto'
alias ls='/bin/ls $LS_OPTIONS'
which works great.
ls -F | grep /\$
but will break on directories containing newlines. Or the safe, POSIX sh way (but will miss dotfiles):
for i in *; do test -d "./$i" && printf "%s\n" "$i"; done
.flac is the filetype.
/Volumes/Music/FLAC is the destination.
Replace .py with .rb or .java to get the LOC of that particular filetype. An alternative is http://www.commandlinefu.com/commands/view/2812/make-a-statistic-about-the-lines-of-code
Specify the size in bytes using the 'c' option for the -size flag. The + sign reads as "bigger than". Then execute du on the list; sort in reverse mode and show the first 10 occurrences.
Prints the path/filename and sparseness of any sparse files (files that use less actual space than their total size because the filesystem treats large blocks of 00 bytes efficiently).
There's nothing particularly novel about this combination of find, grep, and wc, I'm just putting it here in case I want it again.
ack search recursively by default
| sed "s/$/\/(1024\*1024\*1024)/" | bc
to get size in GB
Find files in a specific date range - in this case, the first half of last year.
-newermt = modification time of the file is more recent than this date
GNU find allows any date specfication that GNU date would accept, e.g.
find . -type f -newermt "3 years ago" ! -newermt "2 years ago"
find . -type f -newermt "last monday"
Example above will recursively find files in current directory created/modified in 2010.
Original submitter's command spawns a "grep" process for every file found. Mine spawns one grep with a long list of all matching files to search in. Learn xargs, everyone! It's a very powerful and always available tool.
