ls -l | grep ^-

ls -l | sed "$(while (( ++i < 5 )); do echo "N;"; done) a -- COMMIT --"

Functions: ls sed

specially usefull for sql scripts with insert / update statements, to add a commit command after n statements executed.

( last ; ls -t /var/log/wtmp-2* | while read line ; do ( rm /tmp/wtmp-junk ; zcat $line 2>/dev/null || bzcat $line ) > /tmp/junk-wtmp ; last -f /tmp/junk-wtmp ; done ) | less

Functions: last ls read rm zcat

When your wtmp files are being logrotated, here's an easy way to unpack them all on the fly to see more than a week in the past. The rm is the primitive way to prevent symlink prediction attack.

ls -R .
ls -d */* | sed -e 's/^/\"/g' -e 's/$/\"/g' | xargs mv -t $(pwd)

Functions: ls mv sed xargs

You WILL have problems if the files have the same name.

Use cases: consolidate music library and unify photos (especially if your camera separates images by dates).

After running the command and verifying if there was no name issues, you can use

ls -d */ | sed -e 's/^/\"/g' -e 's/$/\"/g' | xargs rm -r

to remove now empty subdirectories.

ls -1 /lib/modules
2010-03-01 06:30:12
Functions: ls

no need for rpm, no need for piping to another command. also no real fu but lacking in unnecessary complexity and distro specific commands.

lsli() { ls -l --color "$@" | awk '{ for(i=9;i<NF;i++){ printf("%s ",$i) } printf("%s\n",$NF) }'; }

User: quigybo
Functions: awk ls

displays the output of ls -l without the rest of the crud. pretty simple but useful.

ls -RAx | grep "svn:$" | sed -e "s/svn:/svn/" | xargs rm -fr
ls *.wav | while read f; do lame "$f" -o "$(echo $f | cut -d'.' -f1)".mp3; done;
ls *.jpg | grep -n "" | sed 's,.*,0000&,' | sed 's,0*\(...\):\(.*\).jpg,mv "\2.jpg" "image-\1.jpg",' | sh
ls . | xargs file | grep text | sed "s/\(.*\):.*/\1/" | xargs gedit
newest () { find ${1:-\.} -type f |xargs ls -lrt ; }
ls -l | sed -e 's/--x/1/g' -e 's/-w-/2/g' -e 's/-wx/3/g' -e 's/r--/4/g' -e 's/r-x/5/g' -e 's/rw-/6/g' -e 's/rwx/7/g' -e 's/---/0/g'
ls -t1 | sed 1d | parallel -X rm
2010-01-28 12:28:18
Functions: ls sed

xargs deals badly with special characters (such as space, ' and "). To see the problem try this:

touch important_file

touch 'not important_file'

ls not* | xargs rm

Parallel https://savannah.nongnu.org/projects/parallel/ does not have this problem.

ls -Q * | xargs -p rm
2010-01-27 02:46:49
User: temp_reg
Functions: ls xargs

ls -Q will show the filenames in quotes. xargs -p rm will print all the filenames piped from ls -Q and ask for confirmation before deleting the files.

without the -Q switch, if we have spaces in names, then the files won't be deleted.

ls /usr/bin | xargs whatis | grep -v nothing | less
2010-01-26 12:59:47
User: michelsberg
Functions: grep ls whatis xargs

no loop, only one call of grep, scrollable ("less is more", more or less...)

for i in $(ls /usr/bin); do whatis $i | grep -v nothing; done | more
find / \( -local -o -prune \) \( -perm -4000 -o -perm -2000 \) -type f -exec ls -l {} \;
xdg-open $(ls . | dmenu)

Simple file browser with dmenu, ls, and xdg-open.

ls / | sed -e :a -e 's/^.\{1,15\}$/&_/;ta'

Functions: ls sed

the sql command lpad and rpad using sed

for lpad, invert the &_ with _&:

ls / | sed -e :a -e 's/^.\{1,15\}$/_$/;ta'
ls | sed "/^/=" | sed "N;s/\n/. /"
ls | sed -n '1h;2,$H;${g;s/\n/,/g;p}'

Functions: ls sed

searching for sed to make a csv, I found the solution from Mr. Stolz in http://funarg.nfshost.com/r2/notes/sed-return-comma.html

you can also to use:

tr "\n" "," ;

But I was looking for a sed way =)

ls -lah --color=always | most
2010-01-04 22:21:13
User: Code_Bleu
Functions: ls

Even though --color is an option for 'ls' it will not display in color when doing 'ls -lah --color=always | less' to have color output when doing a directory listing and piping it out to page through results, replace less with most.

To install most if not installed, run:

sudo apt-get install most

BACKUP_FILE_SIZE=`eval ls -l ${BACKUP_FILE} | awk {'print $5'}`; if [ $BACKUP_FILE_SIZE -le 20 ]; then echo "its empty"; else echo "its not empty"; fi

Functions: awk echo ls

If you gzip an empty file it becomes 20 bytes. Some backup checks i do check to see if the file is greater than zero size (-s flag) but this is no good here. Im sure someone has a better check than me for this? No check to see if file exists before checking it's size.
