You can use below


mv usr/sbin/appl/tmp/logfile.txt usr/sbin/appl/tmp/logfile_`date +"%d%b%y"`.txt
find usr/sbin/appl/tmp/logfile*.txt -mtime +21 -exec rm {} \ ;

Its not an easy question to answer :)

you can start with below link..

List of operating systems - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/List_of_operating_systems)

You can use awk command to get the desired output.. regarding ??? not sure what inbtw process happening in your script..


awk '{print $1" "$1" "$4}' Input1.txt

Have you tried the sort command which I have provided above?

why arent u using sed?


sed 's/$/;/g' filename

redirect the output of your top command to a file and start that as background process run sleep for 5 mins and then kill the background process.

sort -t, -k1,1 -u input.csv

try..


awk '{lines[NR] = $0}!/>/&&length($0) < 11 {print lines [NR-1]; print lines [NR]} ' example.txt

try to put the full path here

LOG_FILE=/arbor/integ_fx/rahul_raj/itsr_5652/error.log

looking at your req i suggest you using
or else it should be

vidya> v=date
vidya> echo `$v`
Mon Jul 22 12:00:44 CEST 2013
vidya> echo `$v`
Mon Jul 22 12:00:48 CEST 2013
vidya> echo `$v`...

try...

awk 'NR==FNR{v=$1;$1="";A[v]=$0;next}
{print $0" "A[$2]}' file2 file1

how about below..


awk -F"," '{gsub("/","\",\"",$2);OFS=","}1' filename

there is no not command in ksh. try ! or test

u can.. but bit messy though


awk '{v=substr($0,45,22);sub(/[ ]+/," ",v);print substr($0,0,44) v substr($0,68)}' filename

My fav for this is..


awk 'c-->0;$0~s{if(b)for(c=b+1;c>1;c--)print r[(NR-c+1)%b];print;c=a}b{r[NR%b]=$0}' b=0 a=2 s="ACCOUNT" require.txt


b is number of lines above pattern and a is...

you are missing one closing curly bracket at the end.

you have to use the named pipes for this..


mkfifo out.pipe err.pipe
exec 3>&1 4>&1
tee Menu_`date +"%d-%m-%Y"`.log < out.pipe >&3 &
pid_out=$!
exec 1>out.pipe
tee Menu_`date...

you can try ignoring the directory


find ./ -type d \( ! lost+found \) -type f -name "*.csv" -mtime +6 -exec rm -f {} \;

if you consider it as warning messages

redirect the find output...

are you using bash?

if yes below can be used

${parameter^} # Convert the first character in ${parameter} to uppercase
${parameter^^} # Convert all characters in ${parameter} to...

try..


awk -F, '{if($3=="win"){A[$1","$2]++}else{B[$1","$2]++}}END{for(i in A){print i","A[i]"win,"B[i]"lose"}}' filename

add below line to your .profile file (I am still unsure about your requirement)


export PATH=$PATH:<<your application installed path>>

Pleas read my reply to your thread.. since you are piping the out put to while it will open a subshell and variable value would be lost once its back to main shell

use
while read line ; do
blah...

in your script define 2 variables (you can directly feed also to awk)

file1=Aggr_New_`date --date='yesterday' +"%m_%d_%Y"`_*.txt
file2=Aggr_New_`date +"%m_%d_%Y"`_*.txt
awk -F"|"...

try below code.. save it in script called banner and enjoy :)


#!/bin/ksh93
# or #!/bin/bash

A=$((1<<0))
B=$((1<<1))
C=$((1<<2))
D=$((1<<3))
E=$((1<<4))
F=$((1<<5))
G=$((1<<6))...
