if you wanted to pull a date from the directory to only list files from datea/timea through dateb/timeb (say March 2 at 6:00 AM to March 8 at 6:00 AM) and move into a new file the output, how is this accomplished? I tried this but no output
#!/bin/bash
FILES=’ls -A1′
OUTFILE=”c:/temp/RRDfilesinrange.txt”
STARTDATE=’date –utc –date “2010-02-27 06:00:00″ %s’
ENDDATE=’date –utc –date “2010-03-02 06:00:00″ %s’
cd C: temp/tsfr-complete
for f in $FILES
do
if [ -f $f ]; then
FDATE=’stat -c “%Z” $f’
if [ $FDATE -ge $STARTDATE ]; then
if [ $FDATE -le $ENDDATE ]; then
‘echo $f >> $OUTFILE’
fi
fi
fi
done

nice stuff!

i learned a lot from the original post, but the comments are a treasure trove!

one thing about the original post, you have a back tick instead of a single quote in the 1st two snippets
ls -l | egrep `^d’ for example should be ls -l | egrep ‘^d’ for the copy / pasters

thanks again ;)

i renamed a directory name with a space in between the directory name within GUI(Graphical User Interface)
which is allowed and now in the shell prompt i.e. in the terminal command mode i want to enter the directory which has a space in between but it does not allows to enter into that directory it says “INVALID DIRECTORY”
is their any alternative solution or trick to enter into the directory with the name having space.please explain
the directory name is “file data”
i tried with — $cd file data but it didnt work out.

I tried with both GNU ls and BSD one and the best option is as someone else posted above:

ls -ld */

one can list directory i simple and easy way by :
1. ls -ltr | grep -e d
2. ls -ld */
3. du

third one is the most easiest way. :-)

$ /bin/ls -l | grep “^d” | cut -d’ ‘ -f8
it’s a neat trick on linux systems.

i’m using /bin/ls and not ls because it may be aliased

Jagan,
du is used to calculate Disk Usage. I want to know did you tweak this command to display directory listing in pwd. Please explain.

Thanx, nice post. I was just thinking of doing it with awk but couldnt get the wildcard working. Now I am one step ahead in my shell knowledge ^^
To Dennis Quek above :
A rather dirty solution but does the job.

ls -l | egrep ‘^d’ | awk ‘$1=” “‘ | awk ‘$1=” “‘ | awk ‘$1=” “‘ | awk ‘$1=” “‘ | awk ‘$1=” “‘ | awk ‘$1=” “‘| awk ‘$1=” “‘| awk ‘$1=” “‘

(forgive me if seeing this code gives someone a heart attack, all i can say is that I’m still learning :P )
I would love if someone can give my code a neater look :)
