You have four lex-generated files - go intothose files and mark all of the functions in them static - this makes their scope local to the C file they live in. Next create a wrapper function that is NOT static.
in file1.c create scanner1() which calls the yylex function or whatever entrypoint you have defined. Create scanner2(), scanner3() and scanner4() in each of ther other files. In the main block, have for extern declarations for scanner1() scanner2() etc.
ld will hide the fact that each of those four modules has functions all named the same:
Assuming I understood your problem.... I didn't get your first problem very clearly either.

Once a time, I did see a way to multiply a file input in bash, but have forgotten how it was done.
Eks.
awk 'FNR==NR {a++;next} ($2 in a) {print $2}' file file
Here you need file two times.
I seen it some like this
awk 'FNR==NR {a++;next} ($2 in a) {print $2}' 2&file (16 Replies)

GM,
I have an issue at work, which requires a simple solution. But, after multiple attempts, I have not been able to hit on the code needed.

diff3
DIFF3(1) General Commands Manual DIFF3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
FILES
/tmp/d3?????
/usr/lib/diff3
SEE ALSO diff(1)BUGS
Text lines that consist of a single `.' will defeat -e.
Files longer than 64K bytes won't work.
