ls command...

[gopunk]

i'm using ibm aix... and i want to know if there's a way to use ls but have it only list a few of the files, then i can hit a key to see more or something. i couldnt' find this in man... or maybe i'm just really stupid...

ls -l | more

the | is a pipe. It will redirect the output of the first command to the second command. So the output of ls -l will be piped to more.

 

[pedrog]

*the 'more' command will do this. You can 'pipe' the output from 'ls' through more like this
*
*%ls | more
*
*It'll list untill the screen is full and wait for you to hit a key

ya like n0c said


If you are only looking for a particular file type (e.g. files beginning with the letter a) you can use wildcards

%ls a*

will list all files starting with the letter a

or

%ls *txt

will list files ending in txt

 

[gopunk]

wow, thanks guys.

i have a question about ls a* though... suppose a is a directory... then it lists allt he contents of teh directory as well. is there a way to get it to just list the name and not the contents?

thanks, also, how do i pipe it so that the results are in columns and not one per line?

 

[n0cmonkey]

teh -d flag will just list directories and not their contents. I dont think you can pipe the output to more in columns...

 

[gopunk]

thanks...

last question, i hope

how do i do it case insensitive? so i can type in ls a*, and get results even when the files start with 'A'?

i tried: ls -i a*, but that doesn't seem to work.

[ is a powerful command, man it sometime. in this case it would be something like "ls -ld [aA]* | more". [] is like an or what is in there. Or in something like [a-z] an a through z.

 

[gopunk]

thanks...

i guess i was looking for something simpler. i actually already know they're all upper case, but thought there might be some flag i could type that would be faster than hitting the caps lock key

but anyways, thanks, i've learned a lot from you guys.

not sure if "less" comes with AIX but its better than more, you can page up/down as well as doing everything more can.


$ less ls



edit- actually I'm curious, we have some AIX machines here at work, I'll log on to one and try less
update- okay, nevermind.. this is what I got :

$ less ls
ksh: less: not found.

hmm. our aix machines have less, but i guess it was installed separately or something.

On my linux box more can do page up and down also...

It works on HPUX also

pressing the 'b' button goes back on page....

return goes forward a single line and space goes forwards a page...

next ask a question about tr

I would recomend you buy a book called Your Unix-Your Ultimate Guide by Sumitabha Das. It's a very good book which walks your through commands and their options and arguements. Along with simple filters and meta characters, shell scripting and a lot more. Really comes in handy.

The Oreilly UNIX administrator's book is also a valuable guide. I use it even though it doesnt mention my OSes of choice. Great refrence.
