Add strings from one file at the end of specific lines in text file

Hello All,

this is my first post so I don't know if I am doing this right.

I would like to append entries from a series of strings (contained in a text file) consecutively at the end of specifically labeled lines in another file.

As an example:

- the file that contains the values to be added (cluster_sizes.txt):

Code:
;size=3
;size=142
;size=21

- the file these entries shall be added to at the end of each line that begins with ">" (rep_sequences.fasta):

Code:
>seq_3453 source=sludge
AGCATTAGATCCATAGACTACAG
>seq_92 source=water 
CAGGATACAGTACACAGTACAGTACA
>seq_24 source=filter
AGTGACAGTACCCCGTAGACAGTA

so the output should look like:

Code:
>seq_3453 source=sludge;size=3
AGCATTAGATCCATAGACTACAG
>seq_92 source=water;size=142
CAGGATACAGTACACAGTACAGTACA
>seq_24 source=filter;size=21
AGTGACAGTACCCCGTAGACAGTA

is this possible with awk or some similar language/ command? I have been searching on the net but don't really know how to get towards the needed information. I am a newbie to this world of text manipulation.

Any help is greatly welcome, thanks in advance!

Gus

textpack(1)						      General Commands Manual						       textpack(1)

NAME
textpack - Pack and unpack Flex files containing text SYNOPSIS
textpack -c FLEXFILE [TEXTFILE] textpack -x FLEXFILE [TEXTFILE] DESCRIPTION
Text Flex files are used for the storage of strings by the games Exult supports. While expack(1) can operate on such files, using textpack to pack and unpack them is more comfortable. The first parameter determines the mode of operation, -c stands for creation, -x for extraction. Creation TEXTFILE (or stdin if it is missing) is read and must conform to the file format (see below). FLEXFILE will be created containing the strings from this input. Extraction The strings contained in FLEXFILE are extracted and written to TEXTFILE (if given, stdout otherwise) in the file format documented below. File Format Empty lines, and lines starting with a pound sign (#) are ignored. Other lines must begin with a number, followed by a colon (:). The num- ber is the index of the string and may be given either in decimal, in octal prefixed with 0; or in hexadecimal prefixed with 0x. Anything following the colon belongs to the string and gets stored in the Flex verbatim. Lines are limited in length to 1024 characters. EXAMPLES
textpack -x text.flx Writes all the strings contained in text.flx to stdout in the format discussed above. textpack -c text.flx strings.list Reads strings.list and puts its contents into the Flex file text.flx Example text file # An example 0:the zeroth string # strings may be empty 1: # holes are allowed, strings 2 to 16 will be empty 17:string seventeen # 13 hexadecimal == 19 decimal, 24 octal == 20 decimal 0x13:nineteen 024:twenty # numbers need not go up 18:eighteen # this will overwrite the definition from above 19:overwritten AUTHOR
