In Chapter 5 exercise numbers
2. Make a list of files in /usr/bin that have the letter "a" as the second character. Put the result in a temporary file.
3. Delete the first 3 lines of each temporary file[/B]
I did solution number 2 I just have to figure out solution number 3
On solution number 2 I typed in
ls /usr/bin/?a* | cp /usr/bin/?a* /tmp
2. Relevant commands, code, scripts, algorithms:
to delete a line using sed you type in
sed '3d' example.txt
3. The attempts at a solution (include all code and scripts):
So If I type
sed '3d' /tmp

I cant figure out how to do it for all the files in directory at the same time.

pkgproto
pkgproto(1) User Commands pkgproto(1)
NAME
pkgproto - generate prototype file entries for input to pkgmk command
SYNOPSIS
pkgproto [-i] [-c class] [path1]
pkgproto [-i] [-c class] [path1=path2...]
DESCRIPTION
pkgproto scans the indicated paths and generates prototype(4) file entries that may be used as input to the pkgmk(1) command.
If no paths are specified on the command line, standard input is assumed to be a list of paths. If the pathname listed on the command line
is a directory, the contents of the directory is searched. However, if input is read from stdin, a directory specified as a pathname will
not be searched.
OPTIONS
-i Ignores symbolic links and records the paths as ftype=f (a file) versus ftype=s (symbolic link).
-c class Maps the class of all paths to class.
OPERANDS
path1 Pathname where objects are located.
path2 Pathname which should be substituted on output for path1.
EXAMPLES
Example 1: Examples of the use of pkgproto.1.
The following two examples show uses of pkgproto and a partial listing of the output produced.
Example 1:
example% pkgproto /bin=bin /usr/bin=usrbin /etc=etc
f none bin/sed=/bin/sed 0775 bin bin
f none bin/sh=/bin/sh 0755 bin daemon
f none bin/sort=/bin/sort 0755 bin bin
f none usrbin/sdb=/usr/bin/sdb 0775 bin bin
f none usrbin/shl=/usr/bin/shl 4755 bin bin
d none etc/master.d 0755 root daemon
f none etc/master.d/kernel=/etc/master.d/kernel 0644 root daemon
f none etc/rc=/etc/rc 0744 root daemon
Example 2:
example% find / -type d -print | pkgproto
d none / 755 root root
d none /bin 755 bin bin
d none /usr 755 root root
d none /usr/bin 775 bin bin
d none /etc 755 root root
d none /tmp 777 root root
EXIT STATUS
0 Successful completion.
>0 An error occurred.

NOTES
By default, pkgproto creates symbolic link entries for any symbolic link encountered (ftype=s). When you use the -i option, pkgproto cre-
ates a file entry for symbolic links (ftype=f). The prototype(4) file would have to be edited to assign such file types as v (volatile), e
(editable), or x (exclusive directory). pkgproto detects linked files. If multiple files are linked together, the first path encountered is
considered the source of the link.
By default, pkgproto prints prototype entries on the standard output. However, the output should be saved in a file (named Prototype or
prototype, for convenience) to be used as input to the pkgmk(1) command.
