how would u use this to remove every line that has the charater "*" in it?

thanks for that, it does help.

thanks for that, that was quite informative.
just wandering how would that script be modified if say there
were multiple arguments?
e.g
arguments "t:w"
if theres no -t
do something
else
...

ive implemented getopt for the command line but have this problem,

#!/bin/sh
text=""
set -- getopt "t" etc .... #sets arguments
while :
do
case "$1" in #gets arguments...

/bin/echo "/$line/d\nwq!" | ex -s file.txt

ive noticed that this only removes one instance of "$line",
how would you remove all instances of $line from the file?

oh interesting. thanks

yep that works. i was just curious
why does this work
/bin/echo "/$line/d\nwq!" | ex -s file.txt
but not this?
echo "/$line/d\nwq!" | ex -s file.txt

just wandering, is there a way to delete the line out of "file.txt" without having to redirect it to a "new_file.txt" , or do we have flush "file.txt" and copy "new_file.txt" into it?

thanks for that

how to add 2 float values to each other?
i tried this and it doesnt work:
#!bin/bash
numone=1.234
numtwo=0.124
total=`expr $numone + $numtwo`
echo $total
thanks

thanks for that

just wandering if anyone knows what kind of algorithm unix join
command is using to join 2 files.
Thanks!

ahhh BINGO!

oh yes, it is linked to gawk i just checked ...
but the result still remains the same.

hmmz strange, im using SunOS as well and mktime is defined,

the first code returns "1102738530" (which is correct)

where the second code returns "-1"

strange indeed. :(

(let me re-edit my question)

This works
#!/bin/sh
awk 'BEGIN {print mktime("2005 07 01 34 30")}
This doesnt
#!/bin/sh
TIME="2005 07 01 34 30"
awk 'BEGIN {print mktime($TIME)}
what could be...

try using
var1=`grep "update process"`

wow, works like a charm now, thanks for that :)

ok i fixed the error,
this is exactly what i tried...
#!/bin/sh
FILE="somefile"
SOMESTRING="some string"

sed "/${SOMESTRING}/,\${/hello there/p;}" ${FILE} | while read text_line; do
echo...

i just tried using that and i get this error
sed: -e expression #1, char 58: Unknown command: `4'
strange indeed ...

thanks for that, just curious what does the ",$p" do?
also i tried combining "sed" with "grep" in this example;
#!/bin/sh
SOMESTRING="some string"

sed "/${SOMESTRING}/,$p" ${FILE} | grep "hello...

got another question, say i wanted to do the same thing but i wanted to start reading from a file starting from a line that contains a certain string, how can i do so?


#!/bin/sh...

ohh i think it must be a problem with the file im trying to read,
i just tried

/home/test >echo "gives Me Output Like This" | awk '{print $1 " " $2 " " $3}'

and it works fine. thanks :)

strange well im outta ideas ... :(

hmmzz, very strange indeed
are u using bourne shell for that script?
