As per requirement if column 2 is NULL then 'N' ELSE 'Y'.

I have written below awk code. But it is not replacing values for first line. :confused:


cat temp.txt
1|abc|3
1||4
1|11|c ...

ps aux | grep -i "hald"

Will print the grep in output.

-v : print all lines that don't match the pattern

try man grep

ps -ef|grep "rams.e $PORT"|grep -v grep | awk '{print $2}'

sar | awk 'NR>2{$2=$3=""}1' | column -t

#!/bin/ksh
record_count_1=`wc -l < file1`
record_count_2=`wc -l < file2`

((result= ${record_count_1} / ${record_count_2} ))

cd /root/admin/files
ls -1 |head -1

Its working for me

you can try this


$ echo "hello:myde:temp:stiker" | cut -d: -f2,4 | tr ':' '-'
myde-stiker

try this


ls -ltr /root/admin/files/file* | head -1 | awk -F "/" '{print $NF}'


here i have set the field seprator as "/" awk -F "/" and $NF means last field

Edit :

$ echo "hello:myde:temp:stiker" | cut -d: --output-delimiter='-' -f2,4
myde-stiker


Sorry for the first code.
Deleted it :)

sed -n '/qwertykeyboard white/,/qwertykeyboard black/p' < inputfile | sed '1d'| sed '$d' > file1
sed '/qwertykeyboard white/,/qwertykeyboard black/d' < inputfile > file2



let me...

ls -ltr /root/admin/files/file* | head -1 | awk '{print $NF}'

Thanks balajesuri for correction and information.

I am using ksh and single bracket works fine for ksh. :)

Why dont you try

print n number of lines after the line containing ERROR


print n number of lines before the line containing ERROR

Which bash version you are using

there was a change between 3.1 and 3.2

if its 3.2 try


if [[ "${ch}" =~ [0-9] ]]


With out double quotes on regex.

Thanks Balasuri for...

You can use regular expression match

if [ "${ch}" =~ "[0-9]" ]

if [ "${ch}" -eq "3" -o "${ch}" -eq "4" ]


Should be


if [ "${ch}" = "3" -o "${ch}" = "4" ]

OR

if [ ${ch} -eq 3 -o ${ch} -eq 4 ]


= for comparing string
-eq for numbers

sed 's#^"##g;s# "#\^_#g;s#" #\^_#g'

HOME="Your name" export HOME

echo "<p><input type=\"text\" name=\"name\" value=\"${HOME}\" /></p>"

#! /bin/ksh
set -A array1 11 12 13 14 15
set -A array2 abc def ghi ijk lmn
i=0
while [ $i -ne ${#array1
} ]
do
echo " Hello ${array1[i]} ${array2[i]}"
(( i = i + 1 ))
done

...

find . -type f -printf "%AY %p\n" | grep "^2010"

ls -ltr /home/backup | tail -1

will give you the latest file in your back up dir

why is error when you trying to pass as parameter ?

This may help :)
