what is the easiest way to "knock off" the just the first line of a file in bash.

I have a data file and I fix the first entry and then delete the entry.  

My problem is that I do not really trust sed on solaris boxes.  I assume that if it works in solaris, it will work in linux  ( ksh & bash ).

what is an easy way to get rid of the first line in a file in solaris ( and should also work in linux and hopefully aix  ).

Cross platform is the key

Why wouldn't you trust sed?

sed "1d" filename

wil work on any platform.

With GNU sed (Linux) you can even change the file "in place":

sed -i "1d" filename.

Without GNU sed you'll have to use (preserving permissions):

cp -p filename filename.$$; sed "1d" filename > filename.$$; mv filename.$$ filename; rm filename.$$

awk is always an anlternative, equally available on any platform:

awk 'NR!=1 {print}' filename

To replace the original file:

cp -p filename filename.$$; awk 'NR!=1 {print}' filename > filename.$$; mv filename.$$ filename; rm filename.$$

Let me see if I understand this.

If I want to use the cross platform script I need to do someting like this for sed ?  

sed "1d" fixes2 > fixes3;  cp fixes3 fixes2  

Seems messy.

If there is a better way I am all ears !!!
