Thanks
Be more precise with your queries. Check for a word in what? If I give you a word what do you want to do with it? When you check for today's date, do you mean find the first line with that date and then list every line from there to the end? Are you trying to say that sometimes you want to list the last n lines of the file and sometimes you want to grep it for a particular word? Or are you saying you are asked for random things and want to be ready for every possibility, including those you haven't thought of yet?

freebsd-file2c
FILE2C(1) BSD General Commands Manual FILE2C(1)
NAME
file2c -- convert file to c-source
SYNOPSIS
file2c [-sx] [-n count] [prefix [suffix]]
DESCRIPTION
The file2c utility reads a file from stdin and writes it to stdout, converting each byte to its decimal or hexadecimal representation on the
fly. The byte values are separated by a comma. This also means that the last byte value is not followed by a comma. By default the byte
values are printed in decimal, but when the -x option is given, the values will be printed in hexadecimal. When -s option is given, each
line is printed with a leading tab and each comma is followed by a space except for the last one on the line.
If more than 70 characters are printed on the same line, that line is ended and the output continues on the next line. With the -n option
this can be made to happen after the specified number of byte values have been printed. The length of the line will not be considered any-
more. To have all the byte values printed on the same line, give the -n option a negative number.
A prefix and suffix strings can be printed before and after the byte values (resp.) If a suffix is to be printed, a prefix must also be
specified. The first non-option word is the prefix, which may optionally be followed by a word that is to be used as the suffix.
This program is typically used to embed binary files into C source files. The prefix is used to define an array type and the suffix is used
to end the C statement. The -n, -s and -x options are useful when the binary data represents a bitmap and the output needs to remain read-
able and/or editable. Fonts, for example, are a good example of this.
EXAMPLES
The command:
date | file2c 'const char date[] = {' ',0};'
will produce:
const char date[] = {
83,97,116,32,74,97,110,32,50,56,32,49,54,58,50,56,58,48,53,
32,80,83,84,32,49,57,57,53,10
