Top Forums UNIX for Dummies Questions & Answers Sed to remove only first line erroneously removes last line too Post 302544608 by yazu on Thursday 4th of August 2011 09:58:43 AM

I believe you do not have the last newline char in your file. Check whether this works:
Code:
 { cat INPUTFILE; echo; } | sed '1d'

NAME
acheck - Check common localization mistakes SYNOPSIS
acheck [OPTIONS] [INPUT_FILE] DESCRIPTION
This program parses a file checking for syntax rules and optionally asking Aspell for checking word spelling. It makes fix suggestions and outputs a corrected file accordingly adding review comments if requested. It tries to find the file type according to the extension or the first lines and loads rules accordingly. It displays lines when they are parse. When an error is found, a menu is displayed. Just press Enter if you don't want to change anything. If a choice suits you, enter the corre- sponding number. If you want to fix it but no choice is correct, enter a space, then you will be asked for a string to replace the high- lighted text. The script will replace the highlighted text with your choice and parse it again for new errors. Here are all the available commands: Enter, ignore. Ignore. Ctrl+L, redraw. Rewrite the last line, suggestions and hints. Space, edit. Edit the highlighted text. E, edit line. Edit the whole line. H, add hint. Add the displayed hint as review comment. Use this if you want the translator to see the corresponding warning or error but you have no correction. N, next line. Skip the rest of this line. X, exit and discard all changes. Quit without saving modifications, the script ask you for confirmation, you have to enter `yes' to exit otherwise parsing starts again at the current mistake. a, add in dictionary. Add the highlighted word to you personal dictionary, capitalized as it is. l, add lowercase in dictionary. Lowercase the highlighted word to add it to your personal dictionary. i, ignore word. Ignore the highlighted word, same as Enter. I, ignore all. Ignore the highlighted word and add it to your session dictionary. OPTIONS
