Combining lines in sed & awk

[astroumut]

Hi All,

I am trying to combine those two lines.

awk -v pwd="$PWD" '{print "cd "pwd"/"$0""  }' temp1 > converter.sh
sed -n '1,50p' longscript.sh

I have long list of commands in my longlist.sh file and it is standard. I would like to create a file and in there; first I want to enter the folder (with awk) and then by using sed, write the commands just under it.

longscript.sh is something like that

#### Creating folders
mkdir 0sdfdata
mkdir 0sdfdata/0rawsdf
cp *.gz 0sdfdata/0rawsdf
gunzip *.gz
....

and in the end, "converter.sh" should be like that;

cd /home/umut/mystars/star1/
#### Creating folders
mkdir 0sdfdata
mkdir 0sdfdata/0rawsdf
cp *.gz 0sdfdata/0rawsdf
gunzip *.gz
....

cd /home/umut/mystars/star2/
#### Creating folders
mkdir 0sdfdata
mkdir 0sdfdata/0rawsdf
cp *.gz 0sdfdata/0rawsdf
gunzip *.gz
....

How can I just combine those two lines?

Thanks

Umut

If you need to run 50 lines of code in longscript.sh over and over, why don't you extract it to a shorter version, say, shortscript.sh and run it with awk this way:

awk -v pwd="$PWD" '{print "cd "pwd"/"$0";sh /path/to/shortscript.sh"  }' temp1 | sh

Of course you have to generate shortscript.sh first (just one-time though). Also the above method eliminates the need of creating converter.sh under each directory.
