I have a file with a list of filenames. I want to work loopwise through the file and operate on each of the listed files. Normally I'd do something like:
for file in `cat $mydir/file-list`
do
echo $file >> $mydir/my.log
cp $mydir/$file $newdir
done
the problem is that my... (1 Reply)
I'm relatively new to Pro*C programming. In the following example:
char name; EXEC SQL SELECT 'John Doe' INTO :name FROM DUAL;
"John Doe" is in positions 0-7, blanks in 8-19, and a null in 20. I would really prefer the null to be in position 8 and I don't care what's after that. I wrote a... (1 Reply)

Hello,
I'm trying to replace the first x number of spaces in a line with a |. Right now I'm using a very inefficient syntax to accomplish the task and was looking to simplify it.

I have just installed AIX 7.1 on a new system, and find that it displays the same annoying behaviour the you find in Linux:
In an xterm, when you quit vim or less, the file listed in the terminal window is blanked out and replaced with whatever was there before.
In vim there is a couple of... (12 Replies)

lex
LEX(1) General Commands Manual LEX(1)NAME
lex - generator of lexical analysis programs
SYNOPSIS
lex [ -tvfn ] [ file ] ...
DESCRIPTION
Lex generates programs to be used in simple lexical analyis of text. The input files (standard input default) contain regular expressions
to be searched for, and actions written in C to be executed when expressions are found.
A C source program, 'lex.yy.c' is generated, to be compiled thus:
cc lex.yy.c -ll
This program, when run, copies unrecognized portions of the input to the output, and executes the associated C action for each regular
expression that is recognized.
The options have the following meanings.
-t Place the result on the standard output instead of in file "lex.yy.c".
-v Print a one-line summary of statistics of the generated analyzer.
-n Opposite of -v; -n is default.
-f "Faster" compilation: don't bother to pack the resulting tables; limited to small programs.
EXAMPLE
lex lexcommands
would draw lex instructions from the file lexcommands, and place the output in lex.yy.c
%%
[A-Z] putchar(yytext[0]+'a'-'A');
[ ]+$ ;
[ ]+ putchar(' ');
is an example of a lex program that would be put into a lex command file. This program converts upper case to lower, removes blanks at the
end of lines, and replaces multiple blanks by single blanks.
