You would use xargs when you get an errror message like "too many arguments", or when you want on the same line the output of more than one command, look :
Hi,
On AIX 5200-07-00 I have a find command as following to delete files from a certain location that are more than 7 days old. I am being told that I cannot use -exec option to delete files from these directories.
Having said that I am more curious to know how this can be done.

Hi all,
Am piping a list of files to "xargs rm -v".
The files may have spaces in their names.
Please advise how do i deal with it... :confused:

hi
Could any one please tell me the option using which we can run multiple commands using xargs
I have list of files, I want to run dos2unix and chmod at one shot on them
I tried google n searched man pages but couldnt really find the solution , please help

I have an overnight script which runs across a large directory to repair permissions and ownership. I also have this command output the list of files affected so that cron can email these as a log file. Previously I had the command in the form:

I have read several docs on these on the web and looked at examples. I can't figure out the difference. In some cases you use one or the other or you combine them.
can someone help me understand this? (1 Reply)
xargs work great when a command gives multiple line output which can be input to another. In my case it is not working coz the second command uses two words in it.
$ scr.sh
gives output like
193740
638102
375449
..
..
another command takes these number as inputs. it works great... (1 Reply)

Hi guys,
I need to know how i can ignore Pipe '|' if Pipe is coming as a column in Pipe delimited file
for eg:
file 1:
xx|yy|"xyz|zzz"|zzz|12...
using below awk command
awk 'BEGIN {FS=OFS="|" } print $3
i would get xyz
But i want as :
xyz|zzz to consider as whole column... (13 Replies)

BOOM(1) CAO-VLSI Reference Manual BOOM(1)NAME
BOOM - BOOlean Minimization
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
SYNOPSIS
boom [-VTOAP] [-l num] [-d num] [-i num] [-a num] [-sjbgpwtmorn]
filename [outname]
DESCRIPTION
BOOM is used for the first step of the synthesis process. It optimizes a behavioural description using a Reduced Ordered Binary Decision
Diagram representation of logic functions. The file filename is the input behavioural description and must be written in vbe(5) format.
The resulting behavioural optimized description is saved with the name outname or input_name_o in vbe(5) format.
ENVIRONMENT VARIABLES MBK_WORK_LIB(1)
indicates the path to the read/write directory for the session.
OPTIONS -V Verbose mode on. Each step of the optimization is displayed on the standard output.
-T Trace mode on. Some debug informations are displayed on the standard output.
-O Reverses initial Bdd variables order.
-A BOOM performs a local optimization and keeps the architecture of the initial description by saving most of the intermediate sig-
nals. This mode is well-suited for big or regular circuits such as multipliers, adders. By default BOOM performs a global opti-
mization and removes most of the intermediate signals so that the outputs are expressed in terms of the inputs or the internal
registers. This mode is well-suited for random circuits such as FSMs.
-P Uses a parameter file input_name.boom describing optimization directives and constraints. (see below for the exact syntax)
# Example of .boom file
#
# The list of auxiliary signals that have to be kept
# during optimization.
# Generally carry signals, ram address signals etc ...
#
BEGIN_KEEP
carry[3:0]
ram_address[3:0]
END
#
# The list of auxiliary signals which assigned
# expression won't be modified.
# Generally it's ram output signals.
#
BEGIN_DONT_TOUCH
ram_out[7:0]
END
-l num Specifies the optimization level [0-3] (default is 0, low level).
-d num Specifies the delay optimization percent (default is 0% delay, 100% surface).
-i num Specifies the number of iterations for the choosen optimization algorithm (for experts only).
-a num Specifies the amplitude during bdd reordering (for experts only).
-sjbgpwtmorn
Specifies which algorithm has to be used for the boolean optimization.
