I am using a Perl script to open a series of files in a loop, separate the paragraph into lines, and output the lines into a new file. The code works perfectly fine, except when the source file is over a certain size the loop gets stuck and won’t move on to the next file. It still does what it is... (0 Replies)
I need to process a file line-by-line using some value from a shell variable
Something like:perl -p -e 's/$shell_srch/$shell_replace/g' input.txt
I can't make the '-s' work in the '-p' or '-n' input loop (or couldn't find a syntaxis.)

I wrote a script to list all lines in a file with Perl. I am having trouble with the looping part of it. My script is supposed to look at the file and as long as the file is larger than the current line it prints a new line.

ratfor
RATFOR(1) General Commands Manual RATFOR(1)NAME
ratfor - rational Fortran dialect
SYNOPSIS
ratfor [ option ... ] [ filename ... ]
DESCRIPTION
Ratfor converts a rational dialect of Fortran into ordinary irrational Fortran. Ratfor provides control flow constructs essentially iden-
tical to those in C:
statement grouping:
{ statement; statement; statement }
decision-making:
if (condition) statement [ else statement ]
switch (integer value) {
case integer: statement
...
[ default: ] statement
}
loops: while (condition) statement
for (expression; condition; expression) statement
do limits statement
repeat statement [ until (condition) ]
break [n]
next [n]
and some syntactic sugar to make programs easier to read and write:
free form input:
multiple statements/line; automatic continuation
comments:
# this is a comment
translation of relationals:
>, >=, etc., become .GT., .GE., etc.
return (expression)
returns expression to caller from function
define:
define name replacement
include:
include filename
The option -h causes quoted strings to be turned into 27H constructs. -C copies comments to the output, and attempts to format it neatly.
Normally, continuation lines are marked with a & in column 1; the option -6x makes the continuation character x and places it in column 6.
Ratfor is best used with f77(1).
