trim spaces in unix for variable
HI Guys I have written a script using awk to split a file based on some identifier and renaming the file based on two values from specific length. ts a fixed width file. When I am trying to fetch the values Code:
a = substr($0,11,10) b = substr($0,21,5); i am getting spaces in a and b values . I have to form a file like a_b.txt but the file is forming as "a _ b .txt" Please help guys. Last edited by Franklin52; 02-09-2012 at 04:29 AM.. Reason: Please use code tags for code and data samples, thank you |

To remove all the spaces in $a and $b Code:
a=${a// /}
b=${b// /} |

Hi when i tried using the way you provided Code:
a = substr($0,11,10)
a1= ${a// /}i got this error Code:
The error context is
a= >>> ${ <<<
awk: 0602-502 The statement cannot be correctly parsed.Last edited by Franklin52; 02-09-2012 at 04:29 AM.. Reason: Please use code tags for code and data samples, thank you |

To trim the spaces in your awk program from the a variable: left spaces: Code:
gsub(/^[ \t]+/, "", a) right spaces: Code:
gsub(/[ \t]+$/, "", a) |

my data is coming as Code:
INDIAINDIABACD 11 INDIAINDIABACD 12 and i split the data into multiple files based in INDIAINDIA and file name will be BACD_11.txt and BACD_12.txt but in this case it is forming as Code:
"BACD 12 .txt" and "BACD 11 .txt" a = substr($0,11,10) a2=gsub(/[ \t]+$/, "", a) b = substr($0,21,5) b2=gsub(/[ \t]+$/, "", b) fn = a2 "_Src" b2 ".txt" using gusb i am not able to trim also it is returning blank to a2 and b2 respectively. This whole code is inside awk ---------- Post updated at 07:01 AM ---------- Previous update was at 05:19 AM ---------- Thanks guys I got that solved.

Try losing the $ signs in the gsub statements.
You cannot assign gsub to a variable, it only returns the exit status What is a sample input line? |
