How to transfer one line to another in Unix

Suppose i have the following input:

BSCTMC             A13728,  J02448,  L13668,  M14730,  A12868,  C11347,
                   L14203,  C02285,  A14419,  BO0797,  S12666,  M12653,
                   D04841,  S02825,  T14713,  L15004,  C01972,  E12057,
                   S13319

I want the A13728, J02448 (and so on) up to S13319 on the same line instead. I want to create a script that saves it to a text file. Thanks for your help.

Simply:

$ xargs < infile > outfile

You can do this with sed by only replacing newlines when the line ends with a comma (GNU sed):

sed ':a; /,$/ { N; ba }; s/\n//g' infile

If you also want to compress the whitespace from the alignment, add s/, */, /gto the sed expressions, i.e.:

sed ':a; /,$/ { N; ba }; s/\n//g; s/,   */  /g' infile

Output:

BSCTMC             A13728,  J02448,  L13668,  M14730,  A12868,  C11347,  L14203,  C02285,  A14419,  BO0797,  S12666,  M12653,  D04841,  S02825,  T14713,  L15004,  C01972,  E12057,  S13319

If you don't care about the space in-between, you can use awk :

awk '{printf "%s", $0}' inputfile > outputfile

Results :

BSCTMC             A13728,  J02448,  L13668,  M14730,  A12868,  C11347,                   L14203,  C02285,  A14419,  BO0797,  S12666,  M12653,                   D04841,  S02825,  T14713,  L15004,  C01972,  E12057,                   S13319

You can do this pretty easily with:

tr -d '\n' < filename.txt > filename-oneline.txt; mv filename-oneline.txt filename.txt
