Another approach:
awk -F, '!$1{$1=s}{s=$1}1' OFS=, file

Try:


awk -F',' 'BEGIN { OFS=","; p=0 } $1 != 0 { p = $1 } { $1 = p }1' file

awk -F',' 'NR==1 {p=$1} {if($1 == 0) {$1=p} else {p=$1}}1' file

To keep it simple, just use

mv -- -9file.jpg 9file.jpg
The special option "--" can be used to delimit the end of the options. This is useful in delimiting non-option arguments that...

Hi,

Try this one,


find . -name "-9file.jpg" | xargs -I '{}' mv {} 9file.jpg

Hi,
Try this,
awk -F: '/myregex/ {gsub(/\//,"",$2);split($2,a,"."); print a[1];}' input_file
cheers,
Ranga:-)

awk -F"[:/]" '/myregex/ { print $(NF-2)}' mytest.txt

No need to cat mytest.txt...
awk -F: '/myregex/ { print $2}' mytest.txt | sed 's;/\{1,\};;'

echo '//mytestserver.bon.com' | sed -r 's //([^.]*).* \1 '
mytestserver

Hope this clears :)

@ctsgnb,

The command also prints the line after the last regex.
Shouldn't it be?
awk '/one/{f=1;x=NR}f{A[++c]=$0}END{while(++d<x-1)print A[d]}' input

Another approach:
awk '/xyz/{if(s){print...

Another one with awk:
awk 'f && /one/{print;exit}/one/{f=1}f' file

Hello Usha,

How about this?

awk -v c=0 '/xyz/&&c++<1 {a=$0;next} /xyz/&&c>0 { a=a"\n"$0;f=a;next} c>0 {a=a"\n"$0;next} END { print f}' input_file

Is this what you are looking for
Input:
this is test
one

"one" is the search string here.

Try this ( don't know if your system will handle it ):
