UNIX for Dummies Questions & Answers

Hi Franklin52,
thanks for your reply....

It is throwing error

awk: cmd. line:2: fatal: cannot open file `
BEGIN{s=sprintf("%-100s", "")}
NR==1{$0=$0 s)}
NR==n{$0=$0 s)}
1' for reading (No such file or directory)

For the "file" mentioned in the script, i have replaced with my filename , and the file exists.

can u give me a script with filename say : FILE01, bcause i am confused with file name and any such key words.

The filename appears 2 times, have you replace them both with your filename?

Code:

awk -v n=`wc -l < file` '
BEGIN{s=sprintf("%-100s", "")}
NR==1{$0=$0 s)}
NR==n{$0=$0 s)}
1' file

Yes.... i replace them both with file name Tect.txt
I saved your script say a.sh in dir /tmp. and in the same path file also exists.
when i run the script sh a.sh , the error occurs mentioned above.
Can u please test in your system and send the correct code. Sample file is like this.

Tect.txt :

HORU(need to add 100 fillers(spaces) here)
D0000000000000000000000000000000000
D0000000000000000000000000000000000
T000A(need to add 100 fillers(spaces) here)

Oops, excuse me, I had some closing parentheses in the code. This should do it:

Code:

awk -v n=`wc -l < file` '
BEGIN{s=sprintf("%-100s", "")}
NR==1{$0=$0 s}
NR==n{$0=$0 s}
1' file

Regards

Still same error ,

awk: cmd. line:2: fatal: cannot open file `
BEGIN{s=sprintf("%-100s", "")}
NR==1{$0=$0 s}
NR==n{$0=$0 s}
1' for reading (No such file or directory)

It works fine for me, have you used backticks (`) around the wc command?
maybe your version of awk doesn't support the -v option, use nawk or /usr/xpg4/bin/awk on Solaris or try this:

Code:

awk '
BEGIN{s=sprintf("%-100s", "")}
NR==1{$0=$0 s}
NR==n{$0=$0 s}
1' n=`wc -l < file` file

Regards

thanks i tried in another server. now the script is working and the file data is displayed. but the file is not appended with spaces as i said.
