how to sort...

[ogniemi]

I have a text file:

fsaffafasfasfd
afafafafa
asfafafasfafasfafa
af
fasf
affafasasfa


and as a sort result I expect lines sored from the shortest to the longes, so:

af
fasf
afafafafa
affafasasfa
fsaffafasfasfd
asfafafasfafasfafa



thx in advance!

Hi

sed 'h;s/././g;G;s/\n/\t/' /input/file | sort | sed 's/.*\t//'

[gray]# or[/gray]

awk '{$0=$0"\t"length($0)}1' /input/file | sort -t$'\t' -k2 -n | awk '{NF--}1'

[gray]# or[/gray]

perl -ne '$l[$.]=$_;END{print sort{length $a<=>length $b}@l}' /input/file

thank you.

in the meantime I found also such script:


#! /bin/sh
#
### lensort - sort by line length
### Usage: lensort [files]

# print each line's length, a TAB and then the actual line.
# By default, awk can run out of fields on long lines;
# setting FS=RS, to make each line one long field, can help.
awk 'BEGIN { FS=RS }
{ print length, $0 }' $* |

# Sort the lines numerically
sort +0n -1 |

# Remove the length and the space and print each line
sed 's/^[0-9][0-9]* //'
