Inserting in sorted rows

Hello Friends,

I have a file with many many rows and I want to insert some numbers in between numbers.
The number must be inserted in "correct sorted order".

1. Input = 1055555

1055555 <-insert here

2. Input = 4000080
4000080 <-insert here

Do you have other solutions aside from this?

cat 1055555 >> Onerow.txt
sort Onerow.txt

Thank you my friend.

awk '!f&&$1>n{$0=n"\n"$0;f=1}1' n="$input" filename

Use nawk or /usr/xpg4/bin/awk on Solaris.

So, you should:
awk '!f&&$1>n{$0=n"\n"$0;f=1}1' n="$input" filename>new\
&&cp filename filename.orig\
&&mv new filename

For input greater than the max value in the file:
awk '!f&&$1>n{$0=n"\n"$0;f=1}1;END{if(!f)print n}' n="$input" filename
