HPUX commands?

Chin Meng — Tue, 27 Feb 2001 06:05:52 GMT

Dear all,

What are the commands that can be used if I wanna to find certain words and then need to replace that words with the new words.

Example, testing1.txt. Inside the testing1.txt has many of "$HOSTNAME" I wanna to replace the "$HOSTNAME" to "$BAAN" for example.

I should used the command like find ./-name..?

Maybe I need the HPUX command for replace the word?

Thank you in advance for whom help me.

Hi,

To change text in a file, you should use 'sed'.

cat yourfile | sed -e 's/\$HOSTNAME/\$BAAN/g' > yourfile.new

should do the job. The 's' in the sed command means 'substitute' and the trailing 'g' means 'globally' (ie every occurence on a line).

The stuff between the slashes is what and to what you want to change.

See the sed(1) manpage for more info on sed and the regexp(5) manpage for info on regular expressions.

Hope this helps,
Rik

Hi Use this line of sed to substitute:
cat yourfile | sed 's, \$HOSTNAME, i\ \$BAAN,g' > yourfile.new

Hello Chin,

why not using "ed"?

find . -exec ed -e '1,$s/\$HOSTNAME/\$BAAN/g' -e'1,$w' {} ";"

that should do the trick...

HTH,
Wodisch

I opt for the use of sed.

cat file | sed -e s/pattern1/pattern2/g > newfile
