[SOLVED] "for loop" command to separate lines in desired format

rpascua · 02-12-2014, 01:57 PM

I have several directories that contain dozens of files and I'm trying to do a word count on each file and display it on screen. Here's the command I'm using.

for i in *; do echo $i \ ; find $i -type f | wc -l; done

The result looks something like this:

dir1
23
dir2
105
dir3
50

I would like the result to look more like this:

dir1 23
dir2 105
dir3 50

Any suggestions?

Here's a possibility:

Code:

find -type f -print0 | xargs -0 wc -l

If you need the columns switched, you could use awk:

Code:

find -type f -print0 | xargs -0 wc -l | awk '{ print $2" "$1 }'

or you you can use a printf instead of print, it works like C printf.

With this InFile ...

Code:

dir1
23
dir2
105
dir3
50

... this sed ...

Code:

sed '$!N;s/\n/ /' $InFile >$OutFile

... produced this OutFile ...

Code:

dir1 23
dir2 105
dir3 50

Looks like you are counting files in a directory ( and subdirecties )

Slight variation on your original

Code:

for i in */;do echo $i $(find "$i" -type f | wc -l);done

If you are after the word count of each file in the subdirs then metaschima's will get that

Note, the trailing / in */
this convinces bash to only condider dirs.

In the find. subshell $() note the "" around $i
this prevents word splitting, therefore will work as desired even if dir has spaces in it

echo -n doesn't put a newline char

This worked for me. Thank you!
