Thanks Ravinder for the reply.
Sorry for not following the code rule.

I will read the man page and update the result here if I found any.

I want to replace a string by contents of file.

I am trying the following sed command:
cat sample | sed "s^<enter description here>^`cat details`^"

But it is not working.

Thanks for the reply. UTF-8 has 3 bytes header before actual data.

Not sure whether I can post 'ant' related question here.
There is a requirement to convert files to UTF-8 format.

So, I tried this simple ant script.

grep -c word filename

First try only grep command and see if it works. If yes, then pipe it to cut command.
Also run 'which grep' to make sure you are running correct version of grep.

Another way:

grep -v -e pattern_1 -e pattern_2 -e pattern_3

Here we invoke grep only once; and this is what you want.

Have you tried using cut ?

Instead of $D=`command`, use D=`command`.

Use

if [ -d dir ]
then
echo dir exists now copy
fi

echo command can append to a read-only file too.

If the file is read-only, with w flag removed, then even echo should not be able to append to the file. But it is possible.

Can anybody explain...

Can we please modify this perl one-liner to print lines between pattern1 and pattern2 in a file?

Currently it prints lines till pattern2.

cat file | sed "s:'TBCD::g"

This is regarding using awk tool to find lines matching between 2 patterns.

cat file | awk '/pat1/,/pat2/'


But it's not working as expected in the following case.

[1]

If pat1 also...

This one-line command will do:

sed -n 100,200p filename | grep -10 pattern

searches for a pattern from line 100 to line 200 of filename and prints 10 lines above and 10 lines below the pattern.

You have $(warning text) function in gmake.

$(warning This is a warning)

prints

This is a warning

to stderr.

You can have this anywhere, no condition of tab.

You need to use eval command.

cat filename | tr -s ' '

This should work. Replaces two or more more spaces with one space.

Hi,

I am using /bin/sh. I want to display the stdout and stderr on the terminal as well as save it in a file, so I'm using this command.

gmake all 2>&1 | tee log

But even if gmake fails,...

ls -l | grep -v '\.sh$'
