Hi All,
I have a file say abc.xml. In this file, I need to search for a pattern “SAP_GATEWAY_HOST”; if this pattern found and the next line also contain the pattern “nwprc03.cos” then I need to replace this pattern “nwprc03.cos” with some other pattern “nwdrc03.apjp”.

I am using the while-loop to read a file.
The file has lines with null-terminated strings (words, actually.)
What I have by that reading - just a first word up to '\0'!
I need to have whole string up to 'new line' - (LF, 10#10, 16#A)
What I am doing wrong?

Now what do I add to this... (3 Replies)

Hi,
I currently have a problem that I need to read a file line by line.
After I read it line by line there are some commands in which I have to change a specific string.(In my case, I have to make a script that changes all the passwords into hash value)
Here is a sample input... (3 Replies)
Hello,
My aim is to search string1 in all lines. When found, find and replace string2 by string3 if possible.

Second line with string1 & string2
Not last line but it contains string1

Here is my first line

algotutor
ALGOTUTOR(1) User Contributed Perl Documentation ALGOTUTOR(1)NAME
algotutor - an interactive program for observing the intermediate steps of algorithms.
SYNOPSIS
algotutor [OPTION] ... DATA ...
DESCRIPTION
algotutor is an interactive program for observing the intermediate steps of algorithms. The target audience is computer science students
and/or anyone who studies algorithms and/or data structures. One can create data files in plain text format (actually perl anonymous
hashes, but one need not care) and let algotutor runs through some predefined algorithm. Then one can step backward and forward through the
execution sequence of the algorithm at different levels of details. It requires perl-Tk.
DATA is the input data. For the dynamic programming algorithms such as lcs and matc, please see the respective entries in the following
list; for other algorithms, it is the file name containing the actual input data.
OPTIONS -a ALGO
Runs the algorithm ALGO. Currently ALGO can be one of:
bst operations on binary search trees
rbt operations on red-black trees (remove() is not implemented yet)
heap operations on heaps -- the remove operation on a heap always removes the top element regardless of the argument
sbs stack-based search on graphs, a variant of depth first search
bfs breadth first search on graphs
prim Prim's minimal spanning tree on graphs
dijk Dijkstra's single-source shortest path on graphs
flwa Floyd-Warshall's all-pair shortest path on graphs (very, very slow)
dom 2-dimensional point domination
graham Graham's scan for convex hull
lcs longest common subsequence -- it requires two strings as the command line arguments. For example, "algotutor -a lcs AGCTATACGATGACT
GTCAGTATAGTCATATG"
matc optimal matrix chain multiplication -- it requires an alternating sequence of integers and matrix names as the command line
arguments. For example, "algotutor -a matc 32 A 35 B 24 C 30 D 36 E 25 F 40 G 34 H 35" means finding the optimal multiplication
sequence of the chain of matrices: A of size 32 by 35, B of size 35 by 24, ... H of size 34 by 35.
-s VERTEX
Use VERTEX as the starting vertex (for sbs, bfs, prim, and dijk)
-i STEP
Display step STEP as the initial image.
-d FILENAME
Dump the picture into FILENAME as a ps file and exit immediately without going into interactive mode.
